Best ResponseYou've already chosen the best response.0I cannot figure out how B is correct because wouldn't only Br be replaced with CN ? And after nitril hydrolysis CN changes to CO2H to give carboxylic acid i'm talking about 28

Best ResponseYou've already chosen the best response.0This is so confusing :/ what i learned was the reaction between KCN and halogenoalkane and its a nucleophilic reaction halogen is replaced with CN and nitril is hyrolysed so CN gets replaced with CO2H
