JEE Main Chemistry question

If a molecule has zero dipole moment, the sigma bonding orbitals used by (at. no. ) are:

(A)Pure
(B)-hybrid
(C)-hybridCorrect
(D)-hybrid

Answer: (C)

Solution

A zero dipole moment in requires a symmetric, planar arrangement of the three identical bonds with no lone pair on , i.e. trigonal planar geometry, as in . This geometry arises from
