Options

A. `CH_(3)-underset(underset(OH)|)(CH)-underset(underset(OH)|)(CH_(2))`
B. `CH_(3)CH_(2)CH(OH)_(2)`
C. `CH_(3)-underset(underset(OH)|)(C)=CH_(2)`
D. `CH_(3)-C=CH`

Answer

4

Explanation

`CH_(3)-CH_(2)-CH_(2)-OH underset((X))(overset("Conc. "H_(2)SO_(4))underset(160-180^(@)C)(rarr)CH_(3)-CH=CH_(2)) overset(Br_(2))(rarr)underset((Y))(CH_(3)-underset(Br)underset(|)(CH)-underset(Br)underset(|)(CH_(2))) underset((Z))(underset((NaNH_(2)),(-2HBr))overset("alc.
