Which of the following reaction takes place at cathode in electro chemical manufacture of adiponitrile from acrylonitrile?

2CH2=CHCN+2H2 O→NC – (CH2)4 – CN+\(\frac{1}{2}\) O2

H2O →2H++\(\frac{1}{2}\) O2+ 2e–

2CH2=CHCN+2H2 O+2e–→NC – (CH2)4 – CN

2CH2=CHCN+2H2 O+2e–→NC – (CH2)4 – CN+2OH–

2CH2=CHCN+2H2 O→NC – (CH2)4 – CN+\(\frac{1}{2}\) O2
