1.	R - CH_(2) - CH_(2)OH can be converted into RCH_(2)CH_(2)COOH. The correct sequence of reactants is
Answer» `PBr_(3), KCN, H^(+)` `PBr_(3), KCN, H^(+)` `KCN, H^(+)` `HCN, PBr_(3), H^(+)` SOLUTION :`RCH_(2) CH_(2)OH OVERSET(PBr_(3))rarr RCH_(2)CH_(2)Br overset(KCN)rarr RCH_(2)CH_(2) CN overset(H^(+))rarr RCH_(2)CH_(2)COOH`.
