Compare the two methods shown fopr the preparartion of carboxylic acids:
Method : `RBrunderset("diethyether")overset(Mg)toRMgBr underset(2.H_(3)O^(+))overset(1. CO_(2))toRCO_(2)H`
`Method 2 : RBroverset(NaCN)toRCN underset(Heat)overset(H_(2)O,HCl)toRCO_(2)H`
whixh onr of the following dtatement correctly descibes this conversion ?
