Assertion: Tertiary alcohols gets converted into an alkene instead of a carbonyl Compounds in the presence of heated metallic copper.

Reason: Tertiary alcohols prefer to undergo dehydrogenation instead of dehydration in the presence of heated copper.

Assertion (A): Phenoxide ion is more stable than carboxylate ion.
Reason (R): The –ve charge is delocalized over two electronegative atoms in carboxylate ion.
