Picture (a)shows p-orbital overlap between carbon and oxygen atoms;picture (b)shows p-orbital overlap between silicon and oxygen atoms.
Based on these pictures,it is expected that
A)carbon and oxygen form better σ bonds than silicon and oxygen,so C-O single bonds are stronger than Si-O single bonds.
B)silicon and oxygen form better σ bonds than carbon and oxygen,so Si-O single bonds are stronger than C-O single bonds.
C)carbon and oxygen form better π bonds than silicon and oxygen,so C=O double bonds are stronger than Si=O double bonds.
D)silicon and oxygen form better π bonds than carbon and oxygen,so Si=O double bonds are stronger than C=O double bonds.
