Nitrogen Containing Compounds Question 155
Question: The correct order of basicity in amines (i) $ C_4H_5NH_2 $ (ii) $ CH_3NH_2 $ (iii) $ {{(CH_3)}_2}NH $ (iv) $ {{(CH_3)}_3}N $ [Kerala CET 2005]
Options:
A) (i) < (iv) < (ii) < (iii)
B) (iv) < (iii) < (ii) < (i)
C) (i) < (ii) < (iii) < (iv)
D) (ii) < (iii) < (iv) < (i)
E) (iv) < (iii) < (ii) < (i)
Show Answer
Answer:
Correct Answer: A
Solution:
Basicity order is $ C_4H_5NH_2<{{(CH_3)}_3}N<CH_3NH_2<{{(CH_3)}_2}NH $ $ {{(CH_3)}_3}N $ is less basic due to steric effect while $ C_4H_5NH_2 $ is less basic due to resonance.
