Question

Which of the following is a strong base?

• A. Benzamide
• B. Butanamine
• C. Nitrobenzene
• D. Benzene

Answer 1

Answer: (B)

Amines are basic in nature due to the presence of lone pair of electron. Hence, they can accept the proton. The basic nature of amine increases with the increasing of +7 (Inductive) effect. Butanamine has the tendency to accept the proton due to the presence of lone pair of electron on nitrogen atom hence, it is a strong base. $C{H}_{3}C{H}_{2}C{H}_2\stackrel{\bullet \bullet }{N}{H}_2$
