Answer 1

On passing electricity through nitrobenzene solution, it is converted into azobenzene. The mass of azobenzene is 728 mg, if the same quantity of electricity produces oxygen just sufficient to burn 96 mg of fullerene (C₆₀)·

Explanation:

\[\ce{8e^- + 2 Ph - NO2 -> Ph - N = N - Ph}\]

\[\ce{OH^- -> 1/4 O2 + 1/2 H2O + e^-}\]

\[\ce{60C + 60 O2 -> 60 CO2}\]

`(96 xx 10^-3)/(60 xx 12) xx 60 xx 4 xx 1/8 xx 182`

⇒ 0.728 gm

= 0.728 × 1000

= 728 m
