For the following reaction :
`(A) CH_(3)CH_(2)CH_(2)Br+KOH to CH_(3)CH=CH_(2)
`+KBr +H_(2)O`

which of the following statement is correct ?

Options

A. is substitution. (B) and (C) are addition reactions
B. (A) and (B) are elimination reactions and (C) is dition reaction
C. (A) is elimination. (B) is substitution and (C) is addition reaction
D. (A) is elimination. (B) and (C) are substitution reactions

Answer

C

Explanation

Br is getting climinated & a `(pi)` double bond is getting created that is conversion of saturated compound to unsaturated one.

(b) t is a substitution reaction because Br group is replaced/ substituted by-Ok group.
(c)
This is an addition reaction as 2 Br groups are getting added conversion of saturated compound to an unsaturated one.
