Question

Find out the number of compound(s) having non zero Dipole moment.

Answer 1

G & J have zero dipole moment

A, C, B, D, E, F, H, I have non-zero dipole moment. A and C are similar to hydrogen peroxide structure and oxygen is $s{p}^3$ hybridized and hence the dipole moment do not cancel each other.
There are 8 structures having non-zero dipole moment.
