### homework 2.45 7th edition

2.45 Consider the bonding in H2CPCHCHO. (a) Draw the most important Lewis structure. Include all nonzero formal charges. (b) Identify the composition of the bonds and the hybridization of each lone pair—for example, by writing s(H1s,C2sp2).

I know question (a) but for question (b) can someone explain to me how I can get the hybridization of O in the molecule?
thanks.

There is a double bond which consists of a pi and a sigma bonds present in C and O. For the sigma bond, since there are three electron densities, its hybirdization should be C2sp2-O2sp2. For the pi bond, since there is a unused electron in its 2p orbital, it will form a pi bond with C2p and O2p.
