(C) When vapours of a tertiary alcohol are passed over hot reduced copper at $300^{\circ} C$,dehydration occurs instead of dehydrogenation,leading to the formation of an alkene.For example,tert-butyl alcohol undergoes dehydration:$CH_3-C(OH)(CH_3)-CH_3 \xrightarrow{Cu, 300^{\circ} C} CH_3-C(CH_3)=CH_2 + H_2O$Primary alcohols undergo dehydrogenation to form aldehydes,and secondary alcohols undergo dehydrogenation to form ketones.

When vapours of an alcohol are passed over hot reduced copper,the alcohol is converted into an alkene quickly. The alcohol is:
