1.

The compound formed by reaction of 1, 1- dichloropropane with Zn can also be prepared by the following reaction

Answer»

3, 4-Dibromohexane with zinc
3-Bromohexane with alco. KOH
both of the above
None of above

Solution :1,1-Dichloro propane on REACTING with Zn gives 3 - hexene
`CH_(3)CH_(2)CHCl_(2)+Zn + Cl_(2)CHCH_(2)CH_(3) to CH_(3)-CH_(2)-CH = underset("3 - Hexene")(CH - CH_(2)-CH_(3))`
CHOICE (1) and (2) also give 3 - hexene
`CH_(3)-CH_(2)-underset(Br)underset(|)CH-underset(Br)underset(|)CH-CH_(2)CH_(3)+Zn to CH_(3)CH_(2)-CH = CH - CH_(2)CH_(3)`
`CH_(3)-CH_(2)-underset(Br)underset(|)CH-CH_(2)CH_(3) + alc.KOH to CH_(3)CH_(2) - CH = CH - CH_(2)CH_(3) + KBr + H_(2)O`
