(B) primary amine ($1^{\circ}$ amine) is an amine where the nitrogen atom is attached to only one carbon atom (i.e.,$R-NH_2$).Let us analyze the given compounds:$1. (CH_3)_3N$: Tertiary amine $(3^{\circ})$$2. (CH_3)_2NH$: Secondary amine $(2^{\circ})$$3. CH_3-NH_2$: Primary amine $(1^{\circ})$$4. CH_3-CH(NH_2)-CH_3$: Secondary amine $(2^{\circ})$$5. C_6H_5NH_2$: Primary amine $(1^{\circ})$$6. C_6H_5NHCH_3$: Secondary amine $(2^{\circ})$$7. (CH_3)_3C-NH_2$: Primary amine $(1^{\circ})$The primary amines are $CH_3-NH_2$,$C_6H_5NH_2$,and $(CH_3)_3C-NH_2$.Thus,the total number of primary amine molecules is $3$.

What is the number of primary amine molecules among the following compounds?
$(CH_3)_3N, (CH_3)_2NH, CH_3-NH_2, CH_3-CH(NH_2)-CH_3, C_6H_5NH_2, C_6H_5NHCH_3, (CH_3)_3C-NH_2$
