In the given sequence of reactions, identify ‘P’, ‘Q’, ‘R’ and ‘S’ respectively {\CH}_2= {\CH}_2 \stackrel{ P}{ ────▸} {\CH}_2_{|}_{\Br}- {\CH}_2_{|}_{\Br} \stackrel{Q}{ ────▸} { \CH}_2= {\CH}- {\Br} \stackrel{R}{ ────▸} \CH \equiv\CH \stackrel{S}{ ────▸}\C_6\H_6

Correct Answer is : Br2,Alc,KOH,NaNH2, Red hot iron tube

{\Br}_2, {\Alc}, {\KOH}, {\NaOH}, {\Al}_2 {\O}_3

{\HBr}, {\Alc}, {\KOH}, {\CaC}_2, {\KMnO}_4

{\HBr}, {\Alc}, {\KOH}, {\NaNH}_2, Red hot iron tube

{\Br}_2, {\Alc}, {\KOH}, {\NaNH}_2, Red hot iron tube
