For Question 15, can someone explain why 2-methylpentan-3-ol is a secondary alcohol?

Because the OH group is attached to a carbon with 2 alkyl groups...

had it been 3-methylpentan-3-ol then it would tertiary because the OH group is attached to a carbon with 3 alkyl groups.

Hope that helps :smile: & you may also want to join this thread:
