Answer»

SOLUTION :(i) `underset("Butan-1-ol")(CH_(3)CH_(2)CH_(2)CH_(2)OH)overset(" RedP ")underset(I_(2))rarr underset("1-Iodobutane")(CH_(3)-(CH_(2))_(2)-CH_(2)-I)`
(ii) `CH_(3)-(CH_(2))_(2)-CH_(2)-Cl overset(" NaI ")underset(" ACETONE ")rarr CH_(3)-(CH_(2))_(2)-CH_(2)-I`
(III) `CH_(3)-CH_(2)-CH=CH_(2)overset(" HI ")rarr CH_(3)-CH_(2)CH_(2)CH_(2)I`
