Question

In the allene (H2C=C=CH2) molecule:

Answer 1

Answer:

Option c

Explanation:

In the allene, $CH_2=C=CH_2$

Central atom forms two sigma bond and two pi bond.

Hybridization of central atom = sp

Hybridization of two terminal C = $sp^2$

Allene is a nonplanar molecules. This is because of the planes of two $CH_2$ groups which are twisted 90 ° to each other.

Therefore, the two H atoms on one C lie above and below the plane defined by the other $CH_2$ group.
