Vedclass · Answer

(A) The basicity of the given compounds is determined by the availability of the lone pair on the nitrogen atom:$1$. $CH_3-C(=NH)NH_2$ (Acetamidine): It is a very strong base because the conjugate acid is stabilized by resonance across two equivalent nitrogen atoms.$2$. $(CH_3)_2NH$ (Dimethylamine): $A$ secondary aliphatic amine,which is a strong base due to the inductive effect $(+I)$ of two methyl groups.$3$. $CH_3-CH_2-NH_2$ (Ethylamine): $A$ primary aliphatic amine,which is a strong base,but less basic than the secondary amine due to fewer $+I$ groups.$4$. $CH_3-CONH_2$ (Acetamide): The lone pair on the nitrogen is involved in resonance with the carbonyl group $(C=O)$,making it very weakly basic.Thus,the correct order of basicity is $1 > 2 > 3 > 4$.

The correct order of basicities of the following compounds is:
$1. CH_3-C(=NH)NH_2$ (Acetamidine)
$2. (CH_3)_2NH$ (Dimethylamine)
$3. CH_3-CH_2-NH_2$ (Ethylamine)
$4. CH_3-CONH_2$ (Acetamide)
