B. Alkanol
C. Alkyne
D. Alkyl amine

Answer 1

Correct Answer - A
`CH_(3)CH_(2)CH_(2)I overset(KOH(alc))rarr underset((A))(CH_(3)-CH=CH_(2))overset(Br_(2))rarr CH_(3)-underset(Br)underset("|")("C")H-underset(Br)underset("|")("C")H_(2)overset(alc. KOH)rarr underset((B))(CH_(3)-C-=CH overset(Na)underset(NH_(3))rarr2CH_(3)-underset((C ))(CH=CH_(2))`
