Question

Number of moles of hydrogen atoms required to get one mole of hydrazobenzene from nitrobenzene is;

• A. 10
• B. 5
• C. 8
• D. 4

Answer 1

The correct option is A 10

Number of moles of $hydrogen$ atoms required to get one mole of $hydrazobenzene$ from $nitrobenzene$ is $10$.
2 $H$ atoms are required for conversion of $nitrobenzene$ to $nitrosobenzene$.
4 $H$ atoms are required to convert $nitrobenzene$ to $phenylhydroxylamine$.
$Nitrosobenzene$ and $phenylhydroxylamine$ combine to form $azoxybenzene$..
2 $H$ atoms are required to convert $azoxybenzene$ to $azobenzene$.
2 $H$ atoms are required to convert $azobenzene$ to $hydrazobenzene$
