A carbonyl group,C=O,and an alkene,C=C,double bonds are both sp2 hybridized.However,the chemistry of these two functional groups is very different.This can be explained by which of the following statements?


A) The bond angle of the carbonyl is larger than the bond angle of the alkene.
B) The electronegative oxygen of the C=O group makes this bond polar.
C) The bond of the C=C is longer that the bond of the C=O.
D) There is more steric crowding in the carbonyl than in the alkene.
