Vedclass · Answer

(B) Compound $A$ is $o$-nitrophenol and compound $B$ is $p$-nitrophenol. $o$-Nitrophenol exhibits intramolecular hydrogen bonding,which reduces its intermolecular attraction,making it more volatile. $p$-Nitrophenol exhibits intermolecular hydrogen bonding,which leads to association of molecules,making it less volatile. Therefore,the vapour pressure of $o$-nitrophenol $(A)$ is higher than that of $p$-nitrophenol $(B)$. Thus,the vapour pressure of $B$ is lower than that of $A$.

Out of the given two compounds,the vapour pressure of $B$ at a particular temperature is:
