1.

Consider the reaction, CH_(3)CH_(2)CH_(2)Br+NaCn to CH_(3)CH_(2)CH_(2)CN+NaBr This reaction will be the faster in

Answer»

ethanol
methanol
N, N'-dimethylformamide (DMF)
water

Solution :`CH_(3)CH_(2)CH_(2)Br` being a `1^(@)` ALKYL halide reacts with `NaCN` by `S_(N)2` mechahnism which is favoured by polar aprotic SOLVENT, i.e., DMF. Thus, option (c) is correct.
