Question

Nitrobenzene is converted into aniline by the process of electroreduction in weakly acidic medium. What is the n-factor of nitrobenzene in this process??
1. 3
2. 6
3. 2
4. 4

Answer 1

there's a formula to calculate n factor for different molecules
n factor = |n1(o.s1) - n2(o.s2)|
n1 = number of moles in reactant
n2 = number of moles in product
os1 = oxidation state in reactant
os2 = oxidation state in product
applying it.. we get nf= 6
