Assertion `:` `Cis-1,3` dihydroxy cyclohexane exists in chair conformation.
Reason `:` In the chair form, there will not be hydrogen bonding between the two hydroxyl groups.

A

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

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false statements.

Text Solution

Verified by Experts

The correct Answer is:
D
Cis-1,3-dihydroxyclohexane exists in chair form as intramolecular H-bonding is possible only in chair form.
