Ethene

Vedclass · Answer

(B) In Hofmann elimination,the quaternary ammonium hydroxide undergoes thermal decomposition to form the least substituted alkene as the major product.Step $1$: The quaternary ammonium iodide is converted to the corresponding hydroxide using moist $Ag_2O$.$(CH_3CH_2CH_2)N^{+}(CH_2CH_3)_3 I^{-} + AgOH \rightarrow (CH_3CH_2CH_2)N^{+}(CH_2CH_3)_3 OH^{-} + AgI$Step $2$: Upon heating,the $OH^{-}$ ion abstracts a $\beta$-hydrogen from the alkyl groups attached to the nitrogen atom.The available $\beta$-hydrogens are on the propyl group (at the $\beta$-carbon) and the ethyl groups (at the $\beta$-carbon).Removal of $\beta$-hydrogen from the ethyl group yields ethene $(CH_2=CH_2)$.Removal of $\beta$-hydrogen from the propyl group yields propene $(CH_3CH=CH_2)$.According to the Hofmann rule,the less substituted alkene is the major product. Since ethene is less substituted than propene,ethene is the major product.
