Write the equations for the preparation of 1- iodobutane from (i) 1- butanol(ii) 1-chlorobutane(iii) but -1-ene.

Answer»

Solution :(i) `underset("1-Butanol ") (CH_(3)CH_(2)CH_(2)CH_(2)OH) OVERSET(P + I_(2)) to underset("1-Iodobutane") (CH_(3)CH_(2)CH_(2)CH_(2)I)` <BR> (ii) `underset("1-Chlorobutane ")(CH_(3)CH_(2)CH_(2)CH_(2)Cl) underset("Finkelstein reaction ") overset("KI/acetone, " Delta) to underset("1-Iodobutane")(CH_(3)CH_(2)CH_(2)CH_(2)I)`
(iii) `underset("But 1-ene")(CH_(3)CH_(2)CH) = CH_(2) underset("Anti - Markovnikov ADDITION ") overset("HBR, peroxide") to underset("1-Bromobutane")(CH_(3)CH_(2)CH_(2)Br) underset ("Finkelslein reaction ") overset("KI/acetone,"Delta ) to underset("1-Iodobutane") (CH_(3)CH_(2)CH_(2)CH_(2)I)`
