$R_3NH^{+}$

Vedclass · Answer

(D) The stability of substituted ammonium ions in the gas phase is determined by the inductive effect of the alkyl groups. Alkyl groups are electron-donating ($+I$ effect). As the number of alkyl groups attached to the nitrogen atom increases,the positive charge on the nitrogen is dispersed more effectively due to the electron-donating nature of the alkyl groups. Therefore,the stability order is $R_3NH^{+} > R_2NH_2^{+} > R-NH_3^{+} > NH_4^{+}$. Thus,$R_3NH^{+}$ is the most stable species.
