The water molecule has similar bond vibrations to carbon dioxide. Decide whether the symmetric, asymmetric, and bending vibrations in water will result in the absorption of IR radiation.

Hello everyone today. We are being given the following problem. Consider the sulfur dioxide molecule which has the same bonding vibrations as carbon dioxide which of the following bond vibration. And sulfur dioxide will cause I. R. Or infrared radiation to be absorbed. Well first you must consider the structure of sulfur dioxide surfer dioxide is presented in the following structure. So you have a sulfur in the middle and you have two oxygen's on either side With a lone pair on Sulfur and three lone pairs on each oxygen. And this geometry the electronic geometry would be considered bent. So the geometry present is of a bent shape and that is taken into account all of the electrons in the shape that this molecule. Yes, one thing that we have to know is that oxygen according to our periodic trends is more electro negative. So oxygen it's more electro negative. I believe it is E. N. Than our sulfur. And due to this bent geometry. So as well as being more electro negative than sulfur. And with the bent geometry that this molecule assumes the dyp whole moment, the die pole moment won't cancel out and the dipole moment is the distribution of electrons. So because oxygen is more electro negative than our sulfur, the electrons will generally be pulled more towards oxygen. And so they go into this direction here and so they will not cancel each other out because they are pointing in different directions. And so as a result we're going to have bent, we're gonna have symmetric stretch, asymmetric stretch and bending, vibrations, meaning the answer is actually all of the above. And so with that we've answered the question overall, I hope that this helped, and until next time.
