In the given reaction, `NH_3+RX to underset((1^@))(R NH_2)+RX to underset((2^@))(R_2 NH)+RX to underset((3^@))(R_3N) + RX to R_4 N^(o+)X^-`
Select an appropriate statement(s) about the reaction.

Options

A. In this reaction `NH_3` is the nucleophile
B. In this reaction RX is the nucleophile
C. `R_4N^(o+)X^(-)` is called as quarternary ammonium salt
D. Both (a) and,(c)

Answer

D

Explanation

Primary amine obtained behaves as a nucleophile and can further react with alkyl halide to form secondary and tertiary amines and finally quaternary ammonium salt.
`underset" Nucleophile"ddot(" "NH_3) + R -X to underset"Substituted ammonium salt"(R overset(o+)NH_3X^-)`
`underset((1^@))(RNH_2)+RX to underset((2^@))(R_2NH) overset(RX)to underset((3^@))(R_3N) overset(RX)to underset"Quaternary ammonium salt"(R_4N^(o+)X^-)`
