Hydrogen: Acid

: A hydrogen is more acidic if the remaining molecule (the conjugate base) is stable after the proton leaves. Resonance, where the remaining negative charge can spread out over several atoms, is a common way this stability is achieved.

An (or acidic hydrogen) is a hydrogen atom in a molecule that can be released as a proton ( H+cap H raised to the positive power ) when reacting with a base. What Makes a Hydrogen Acidic? acid hydrogen

: In organic chemistry, hydrogens attached to a carbon right next to a carbonyl group ( ) can also be acidic due to resonance stabilization. : A hydrogen is more acidic if the
