Diethyldimethyl ammonium halide

Vedclass · Answer

(A) The reaction is Hofmann elimination.Substrate $A$ is diethyldimethyl ammonium halide,which reacts with moist $Ag_2O$ (forming $AgOH$) to produce the quaternary ammonium hydroxide.$(CH_3CH_2)_2N^+(CH_3)_2X^- + AgOH \rightarrow (CH_3CH_2)_2N^+(CH_3)_2OH^- + AgX$Upon heating,the quaternary ammonium hydroxide undergoes Hofmann elimination to form the alkene and the tertiary amine.$(CH_3CH_2)_2N^+(CH_3)_2OH^- \xrightarrow{\Delta} CH_3CH_2N(CH_3)_2 + CH_2=CH_2 + H_2O$

Identify substrate $A$ in the following reaction.
$A + AgOH \xrightarrow[ii) \Delta]{i) \text{moist } Ag_2O} CH_3CH_2N(CH_3)_2 + CH_2=CH_2$
