Question

-Loss of hydrogen halide from alkyl halide gives
A-alkenes
B-alkanes
C-alkynes
D-halogens

Answer 1

loss of hydrogen halide from alkyl halide gives alkenes

Answer 2

Answer:

The loss of the hydrogen halide ( HX ) from the alkyl halide ( haloalkanes ) gives alkene.

Therefore, option A) alkenes is correct.

Explanation:

Given data,

The loss of the hydrogen halide ( HX ) from the alkyl halide ( haloalkanes ) gives:

As we know,

• Alkyl halides are compounds in which one or more than one of the hydrogen atoms is replaced by the halide group ( X - F, Cl, Br, I ).

• Alcoholic KOH is used in the dehydrohalogenation of the alkyl halides to give alkenes.

The general reaction:

• $CH_{3} CH_{2}X + alc.KOH \rightarrow CH_{2}=CH_{2} + KX + H_{2}O$

Let us take the alkyl halide: $CH_{3}CH_{2}Br$ ( bromoethane )

• $CH_{3} CH_{2}Br + alc.KOH \rightarrow CH_{2}=CH_{2} + KBr + H_{2}O$

Hence, the loss of the hydrogen halide ( HX ) from the alkyl halide ( haloalkanes ) gives alkene.
