Question

Phenols and alcohols both have same -OH group but still phenols are sparingly soluble in water. This is because:

• A. They have high molecular mass
• B. They have non-polar aryl group.
• C. They ionize readily to form more stable phenoxide ion
• D. They have high boiling points.

Answer 1

The correct option is B

They have non-polar aryl group.

The non-polar aryl groups is very large in size and it almost completely marks the polar character of the -OH group.
