Question

Which of the following is most basic in nature?

• A. $N{H}_3$
  
• B. $C{H}_{3}N{H}_2$
  
• C. $(C{H}_3{)}_{2}NH$
  
• D. $C_6{H}_{5}NHC{H}_3$
  

Answer 1

The correct option is C $(C{H}_3{)}_{2}NH$


$(C{H}_3{)}_{2}NH$ is most basic because two electron releasing groups are present on Nitrogen. Aniline is less basic than aliphatic amines and ammonia. The basic character of amines follow the order
$(C{H}_3{)}_{2}NH>C{H}_{3}N{H}_2>N{H}_3>C_6{H}_{5}NHC{H}_3$
Aromatic amines are even less basic than ammonia due to involvement of lone pair of nitrogen with the ring with which $N$ is directly attached.
Hence, (c) is the correct option.
