Text Solution

Verified by Experts

The correct Answer is:
B
`overset(beta)(H_(3))underset(Br)underset(|)overset(alpha)(C) - C overset(beta)(H) - CH_(2) - CH_(3) underset(-KBr, -H_(2)O)overset(alc.KOH)rarr underset(("Major 80%"))underset("But-2-ene")(H_(3)C - CH )=CH - CH_(3) + underset(("Minor 20%"))underset("But-1-ene")(CH_(2) = CH - CH_(2)) - CH_(3)`
