Question

1,1 dimethyl cyclohexane is optically inactive because

Answer 1

Answer:

cis-1,2-Dimethylcyclohexane is achiral, not because there is a plane of symmetry, but because it consists of two enantiomeric conformations which interconvert rapidly via ring flipping at normal temperatures. This is exactly the same case as amine inversion.

Answer 2

Answer:

Due to the plane of symmetry and the amine inversion, the compound 1,1 dimethyl cyclohexane is optically inactive.

Explanation:

The compound 1,1-dimethyl cyclohexane is a compound with basic cyclohexane in which at the 1 position two methyls are attached.

The compound 1,1-dimethyl cyclohexane is optically inactive due to the presence of a plane of symmetry in the molecule. The presence of the sigma plane of symmetry makes it optically inactive in nature also it consists of two enantiomeric conformations which interconvert rapidly via ring flipping at normal temperatures same as it happens in the amine inversion.

Hence, the 1,1 dimethyl cyclohexane is optically inactive because of the amine inversion and plane of symmetry.
