Solution :(i) Chlorobenzene to biphenyl (Fittig reaction) <BR>
(II) Propene to 1-iodopropane (ANTI- Markovnikov ADDITION)
`CH_(3)CH = CH_(2) underset("Peroxide")overset(HI) to underset("1-Iodopropane") (CH_(3)CH_(2)CH_(2)I)`
(III)2-bromobutane to but-2-ene
`CH_(3)CH_(2)underset(Br)underset(|)CHCH_(3) overset("Alc.KOH") to underset("But -2-ene") (CH_(3)CH = CHCH_(3)) `
