Since life on earth depends on it being a liquid and serving as a medium in which most chemical reactions (organic and inorganic) take place, it is difficult to immagine what would happen if it all turned to gas. freddymtz27 is waiting for your help. A. bent B. linear C. pyramidal D. tetrahedral Weegy: A molecule with a triple bond would be linear in shape. Water molecules in the bent shape are polar. Figure 3 below shows a comparison between carbon dioxide and water. This drawing is linearâa straight line. of potassium nitrate per 125 g of B. B. Insects which walk on water would fall through. 1 Answer mrpauller.weebly.com Jan 19, 2016 VSEPR theory tells us water has a bent shape. so if water, which is a bent molecule errr.. becomes linear for a day what would happen? Water has a bent geometry, with 104.5°. MEDIUM. At best, the method is able to differentiate between a bent and linear molecule. So I wouldn't have a life. Because of the shape, the dipoles do not cancel each other out and the water molecule is polar. 2) Since water is a polar molecule, hence, the given statement is false. If water were a linear molecule, (a) Would it still. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. is done on EduRev Study Group by Class 11 Students. The electronegativity of oxygen creates a dipole moment in the molecule Explanation: The central oxygen atom has four pairs of electrons. explain, 1. Students also viewed these Organic Chemistry questions. are solved by group of students and teacher of Class 11, which is also the largest student community of Class 11. A complex reaction is believed to have a net reaction of 2 A + 3 B −> C + 2 D. Which mechanism below is consistent with this net reaction? This makes the water molecules very strong dipoles that attract each other with unusual force. Answered Which statement would be true about a water molecule if it had a linear shape? If we changed the shape of water molecules to linear, those molecules would no longer be polar, because each opposite end would be positive leaving the oxygen center to be positive. Unlike carbon dioxide, water is not a linear molecule. Carbon dioxide and water are both very common molecules on Earth. Water molecule is linear in shape. The water molecule consists of an oxygen atom core with two hydrogen atoms attached at an angle of 102.5° at a distance of 0.0957 nm (Kjaergaard et al. If water were a linear molecule, (a) Would it still be polar, (b) Would the water molecules still be able to form hydrogen bonds with one another? Therefore, no net dipole moment would be found for water, as in the case of molecule. Consequently, molecules of water would no longer have this strong attraction for one another and water at room temperature would most likely be in the gaseous form like carbon dioxide. Water is a tasteless, odorless liquid at ambient temperature and pressure.Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour. As a consequence, water molecules are liquid at room temperature because they tend to stick to one another more than other less polar molecules that have a similar shape such as H2S. C8H18+O2→ Insects which walk on water would fall through. There is really only one way my life would be different and that is that I wouldn't exist. A naïve attempt at writing its structure out in full is HâOâH. Carbon dioxide molecules [â¦] Carbon dioxide (CO 2 ) is a linear molecule. Students also viewed these Organic Chemistry questions. If the molecule were linear rather than bent, the electron distribution would be even, not uneven, so the molecule would NOT be polar. Whatâs naïve about this? A water molecule is not linear because of the electron structure of the oxygen atoms in the water molecules. Water would no longer be strongly attracted to itself or other polar molecules. Give reasons for the following :
(i) Covalent bonds are directional while ionic bonds are non-directional. So both the â¦ Explain why the $\mathrm{CH}_{4}$ molecule is not square planar, although its Lewis structure makes it look as though it could be. Each water molecule is not linear, but bent, because oxygen has a greater share in those electrons. I went to a Thanksgiving dinner with over 100 guests. Ask your question. Water molecule is a polar molecule due to angular shape (due to presence of lone pair of electrons on oxygen). It would be a nonpolar molecule. The electronegativity of oxygen creates a dipole moment in â¦ Also, boiling water would no longer be hot enough to cook food. Another way to think of this is that the "pull" of the electrons toward the oxygen from the bond on the left will be cancelled out by the "pull" of the electrons from the bond on the right. Let's look again at the linear depiction of the water molecule. Chemistry Bonding Basics Properties of ionic, covalent, and metallic compounds. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. can anyone tell me what is the right answer for this question? Water is a bent molecule because of the two lone pairs on the central oxygen atom. C) Soap works by making water into a nonpolar liquid which grease can dissolve in. The properties of molecules correlate with their structures; for example, the water molecule is bent structurally and therefore has a dipole moment, whereas the carbon dioxide molecule is linear and has no dipole moment. Now, if water were linear the O-H bonds would still be polar -- they would each have a positive and a negative end -- but because they point in opposite directions the molecule as a whole would be completely non-polar. A molecule is an aggregation of atomic nuclei and electrons that is sufficiently stable to possess observable properties â and there are few molecules that are more stable and difficult to decompose than H 2 O. C8H18+O2 →. The electron group geometry for a molecule with four electron pairs is tetrahedral, as was seen with $$\ce{CH_4}$$. water. The hydrogen bonding character of water would change, resulting in that ice would no longer be less dense than liquid water, and therefore ice would sink to the bottom of bodies of water. If water were a linear molecule, (a) Would it still be polar, (b) Would the water molecules still be able to form hydrogen bonds with one another? This drawing is linearâa straight line. :D. Water's bent structure leads to its polar nature, which is the cause for most of its unique properties. If the molecule was linear, it would no longer be a polar because the bond dipoles between the oxygen and hydrogen would even out. We will take a multi-centered molecular orbital approach instead of the two-centered valence bond/hybrid approach discussed previously. So water would no longer have surface tension.
