What is a catechol ring?

A catechol is an unsaturated six-carbon ring (phenolic group) with two hydroxyl groups attached to adjacent carbons (dihydroxyphenol).

What is a Diphenol?

: a chemical compound (as pyrocatechol or resorcinol) containing two phenolic hydroxyl groups.

Is biphenyl acidic or basic?

The 3-nitroaniline is an organic base; there is a lone pair of electrons on the nitrogen atom of the amino group, making 3-nitroaniline a Lewis base (an electron pair donor). Under these conditions biphenyl has neither an acidic proton nor a lone pair of electrons to donate, and is considered a neutral compound.
