Question

Dehydrating agent and dehydrohalogenating agents among the following are respectively :

• A. conc. $H_2{SO}_4,{Al}_2{O}_3$
• B. ${Al}_2{O}_3,conc.H_2{SO}_4$
• C. conc. $H_2{SO}_4$, Alc. $KOH$
• D. Alc. $KOH$, conc. $H_2{SO}_4$

Answer 1

The correct option is C conc. $H_2{SO}_4$, Alc. $KOH$

$Conc.H_{2}S{O}_4$ is used to remove water from any molecule (dehydration).

$Alc.KOH$ is used to remove $HX$ from any molecule (dehydrohalogenation).

Option C is correct.
