Organic Chemistry

The branch of chemistry that studies compounds containing primarily carbon and hydrogen.

Inorganic Chemistry

The branch of chemistry that studies compounds not primarily composed of carbon and hydrogen.

Physical Chemistry

The branch of chemistry that studies the physical properties and behavior of matter.

Haloalkanes and Haloarenes

A category within Organic Chemistry that focuses on compounds containing halogen atoms (like chlorine, bromine, fluorine) attached to alkanes or aromatic rings.

How do electron-donating groups affect the acidity of alcohols?

Electron-donating groups decrease the acidity of alcohols by making the hydroxyl group less likely to lose a proton.

Oxidation of Alcohols

Alcohols can be oxidized to form aldehydes or ketones, depending on the structure of the alcohol.

Hydrogen Bonding in Phenols

Phenols form stronger hydrogen bonds than alcohols because the aromatic ring helps stabilize the hydrogen bonding.
