Homework Answers
5) option B is correct
Explanation: A double bond functional group is called an alkene
6) option D is correct
Explanation: If -OH group is attached to a carbon atom which is attached to two other carbon atoms is called secondary alcohol.
7) option B is correct
Explanation: alcohols have strong intermolecular forces due to the presence of strong hydrogen bonding. hydrocarbon has weak intermolecular forces due to the presence of weak vannderwaal forces of attraction.
8) option D is correct
Explanation: straight chain alkanes has highest boiling point due to the presence of more vanderwaal forces of attraction.
9) option D is correct
Explanation: Amides have highest boiling point due to the presence of strong hydrogen bonding.
