While separating a mixture of ortho and para nitrophenols by steam distillation, name the isomer which will be steam volatile. Give reason.
Intramolecular H-bonding is present in o-nitrophenol.In p-nitrophenol, the molecules are strongly associated due to the presence of intermolecular bonding. Hence,o-nitrophenol is steam volatile.


Reactant ‘A’ underwent a decomposition reaction. The concentration of ‘A’ was measured periodically and recorded in the table given below:
Based on the above data, predict the order of the reaction and write the expression for the rate law.
