Question

Choose the correct option among the following regarding the molecule given below:

• A. The structure is non-planar
• B. $\mu \ne 0$
• C. The structure is planar
• D. $\mu =0$

Answer 1

$\mu =0$

Allene with odd number of double bonds are planar. Since similar substituent on terminal carbon are at trans position so net dipole moment is zero.
