is ch3cooh an acid or a base and why isnt there hydrogen what is h3

The hydrogen center in thecarboxyl group(−COOH) in carboxylic acids such as acetic acid can separate from the molecule by ionization
CH3COOH → CH3COO⁻+ H⁺
Because of this release of theproton(H+), acetic acid has acidic character.
In solid acetic acid, the molecules form pairs (dimers), being connected byhydrogen bonds.The dissociationenthalpyof the dimer is estimated at 65.0–66.0kJ/mol.

The C−H bond in general is unreactive. In several compound classes, collectively calledcarbon acids, the C−H bond can be sufficiently acidic for proton removal. Unactivated C−H bonds are found in alkanes and are not adjacent to aheteroatom(O, N, Si, etc.). Such bonds usually only participate inradical substitution.
Carbon–hydrogen bonds have a bond energyof about 413kJ/mol
