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

Select one:

a. all the atoms lie in one plane.

b. the ð bonds are delocalised over all three C atoms.

c. the two H atoms on one C lie above and below the plane defined by the other CH2 group.

d. the nonbonding orbitals are full.

e. none of the other options

Answer:

Option c

Explanation:

In the allene, [tex]CH_2=C=CH_2[/tex]

Central atom forms two sigma bond and two pi bond.

Hybridization of central atom = sp

Hybridization of two terminal C = [tex]sp^2[/tex]

Allene is a nonplanar molecules. This is because of the planes of two [tex]CH_2[/tex] 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 [tex]CH_2[/tex] group.
