Assertion : [10]Annulene is not aromatic...

Assertion : [10]Annulene is not aromatic though it contains Huckel number of `pi`-electrons.
Reason:Steric interaction between internal hydrogens makes it non-planar

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Due to severe non-bonded interactions between the internal hydrogen (as shown in figure), the ring assumes non-planar geometry.
