Why are double bonds and triple bonds shorter than single bonds?
1. Why are double bonds and triple bonds shorter than single bonds? 2. VSEPR geometry predicts that the bond angles in formaldehyde (CH20), a trigonal planar molecule, will be 120° throughout all three angles. However, analysis showed that the H-C-H bond angle is slightly smaller at 116.5°, while the two H-C-O angles are slightly larger at 121.8°. Explain this difference in the predicted bond angle vs actual bond angle. 3. VSEPR geometry also predicts that the bond angles in tetrahedral molecules is...

with others? Oil and water don't mix Gasoline and water also do not mix. However, mbul p ciples of Solubility. Why do some substances mix gasoline and oil do mix. To understand solubility we must look at two important characteristics: geometry and bond polarity ionic, nonpolar and polar). From these two characteristics the overall molecular polarity can be determined. The statement "like dissolves like" provides a good basis for understanding solubility. A substance with similar characteristics will mix with another...

C1. Water Water has a number of unique properties that are essential for life. Most of these properties are as a result of the polar nature of water and its ability to form hydrogen bonds. Using your knowledge on the properties of water, answer the questions below. a) Why is it important for water to be a liquid over a broad range of temperatures? [2 marks] b) Why is water referred to as polar and why does its polarity affect...

11. Select one molecule from "Molecules 5' and one molecule from "Molecules 6". Draw the molecules and draw all possible combinations of hydrogen bonds between the two molecules you have chosen [Select your molecules such that one or more hydrogen bond(s) may form.) You will receive points for each correct hydrogen bond, up to the total number of possible hydrogen bonds. You will lose points for incorrect drawings [HINT: You may draw your molecule pairs multiple times, rotating them as...
