Question

In which of the following general overlapping principle is WRONG ? (Where a , b and c can be any one of x , y , z axis respectively) Type of bondPrinciple

TestHub · Accepted Answer

σ bond (A): Formed by head-on overlap along internuclear axis → correct

π bond (B): Formed by sidewise overlap perpendicular to axis → correct

δ bond (C): Formed by overlap of d orbitals (d_ab+ d_ab) with axis along another direction → correct

Option (D) is wrong because:

It shows δ bond with incorrect orientation of internuclear axis (b). δ bonds have a fixed orientation depending on d-orbital symmetry, and this combination does not match proper overlap conditions.
