Detailed Solution

Allene is a non polar molecule. Because symmetry constraints place restrictions on polarity. The symmetry of allene contains perpendicular components.

The polarity vectors cancel out, according to another way of looking at it. The polarity vector that is produced is zero.

The allene will be chiral if it has two different substituents on each of its two carbon atoms because there are no longer any mirror planes.Hence,allene is non planar molecule
