Question
Formaldehyde has the formula H2CO. Describe the bonding between the C and O atoms in VB terms. Hybridization of C atom?
Which statement is correct?
A) The hybridized orbital on C overlaps with a 2p orbital on O to form a bond. The unhybridized 2p orbital on C overlaps with a parallel 2p orbital on O to form the bond.
B) The unhybridized orbital on C overlaps with a 2p orbital on O to form a bond. The hybridized 2p orbital on C overlaps with a parallel 2p orbital on O to form the bond.
C) Two hybridized orbitals on C overlaps with two 2p orbitals on O to form the and the bond.
Explanation / Answer
A) The hybridized orbital on C overlaps with a 2p orbital on O to form a bond. The unhybridized 2p orbital on C overlaps with a parallel 2p orbital on O to form the bond.
because in H2CO carbon undrgoes SP^2 HYBRIDISATION.Hence the central atom carbon has 3 SP^2 hybrid orbitals and one unhybrid p-orbital.all the time the phi-bond is formed by the combination od unhybridised orbital overlappinig is side wise manner..the sigma bond is formed by the end-end overlap of hybridised orbitals.
