. Arrange in order of decreasing basis nature.
CCl3(CH2)NH2 A., CCl3(CH2)2NH2 B. and CCl3CH2NH2 C
A. C > A > B
B. C > B > A
C. B > C > A
D. B > A > C
Sol: Electron withdrawing groups tend to decrease the basicity. In trichloromethyl amines the –CCl3 group is situated near to the –NH2 group anhd withdraws electrons more efficiently and thus decrease its basicity.
