Vedclass · Answer

(C) When vapours of primary $(1^{\circ})$ alcohols are passed over heated $Cu$ at $573 \ K$ $(300^{\circ} C)$,they undergo dehydrogenation to form aldehydes.When vapours of secondary $(2^{\circ})$ alcohols are passed over heated $Cu$ at $573 \ K$ $(300^{\circ} C)$,they undergo dehydrogenation to form ketones.When vapours of tertiary $(3^{\circ})$ alcohols are passed over heated $Cu$ at $573 \ K$ $(300^{\circ} C)$,they undergo dehydration to form alkenes.Among the given options,tert-Butyl alcohol is a tertiary $(3^{\circ})$ alcohol,which undergoes dehydration to form an alkene (isobutylene) under these conditions.

The vapours of an alcohol $(X)$ are passed over $Cu$ heated at $300^{\circ} C$,where an alkene is formed as the product. The alcohol $(X)$ is expected to be $:-$
