Where is resorcinol derived from?

Resorcinol is a phenolic chemical found in dermatologic medications, used in several industrial applications (e.g. photography, tanning, tire manufacturing), and found in roasted barley, canned molasses, adhesives, hair dyes, and cosmetics, among other products.

How would you describe the solubility of resorcinol in water?

Resorcinol (or resorcin) is an organic compound with the formula C6H4(OH)2. It is one of three isomeric benzenediols, the 1,3-isomer (or meta-isomer)….Resorcinol.

Solubility in water 110 g/100 mL at 20 °C
Vapor pressure 0.0002 mmHg (25 °C)
Acidity (pKa) 9.15

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.
