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...

(b) Squalene undergoes catalytic hydrogenation to yield a compound with the molecular formula C30H62. How many double bonds does a molecule of squalene have? (c) How many rings?
Which statements about IS3+ ion is NOT true. A. The molecule has non-polar bonds and is a non-polar molecule. B. The molecule has trigonal planar geometry. C. The central atom does form double or triple bonds. D. There are two ore more resonance structures for the molecule E. The central atoms Violates the octet rule by accepting more than an octet of electrons.
Change the bond between the two carbon atoms in each molecule to a double or triple bond as needed to complete the structure. If the bond should remain a single bond, then you do not need to do anything to the bond. Do not change any other bonds in the molecules.
