Question

Choose the correct option for the following molecule in view of chemical bonding.

• A. non-planar
• B. $\mu \ne 0$
• C. Both A and B
• D. $\mu =0$

Answer 1

The correct option is D $\mu =0$

$\mu$ = 0
Allenes with odd no. of double bonds are planar. The dipole moment vectors in the opposite directions cancel each other. Thus, it has zero dipole moment.
