Question

The melting point of $2$-nitrophenol is lower than that of $4$-nitrophenol and this is because of

• A. intramolecular hydrogen bonding in $2$- nitrophenol
• B. intramolecular hydrogen bonding in $4$- nitrophenol
• C. intermolecular hydrogen bonding in $2$- nitrophenol
• D. hydrogen bonding has no relation to the melting point

Answer 1

The correct option is A intramolecular hydrogen bonding in $2$- nitrophenol

Intramolecular hydrogen bonding.

So,o-nitro phenol has low melting point p-nitro phenol.
