For the following reactions:

Which of the following statement is correct?

Options

A. (a) is subtstitution, (b) and ( c ) are addition reactions
B. (a) and (b)are alimination reaction and (c ) is addition.
C. (a) is alimination, (b) is substitution and (c ) is addition reaction
D. (a) iselimination, (b) and ( c) are substitution reaction

Answer

C

Explanation

`CH_(3)CH_(2)CH_(2)Br + KOH rarr`
`CH_(3)CH = CH_(2) + KBr + H_(2)O rarr `Elimination reaction. Formation of `pi-bond` and conversion of saturated compound into unsaturated compound by the remove of groups or atoms is known as Elimation reaction. `Alc. KOH` acts as base.

Replacement of `Br` by -`OH` known as Substitution Reaction

Conversion of unsaturated compound into saturated into satured compound by the addition of groups or atoms is called as addition reaction. It is electrophilic addition.
