पर्याय

• Formic acid

• Sulphuric acid

• Nitric acid

• Acetic acid

Answer 1

The acid which contains four hydrogen atoms is acetic acid.

Explanation:

Acetic acid has the molecular formula CH₃COOH, which contains a total of four hydrogen atoms (three in the methyl group and one in the acid group). In comparison, formic acid (HCOOH) and sulphuric acid (H₂SO₄) contain two hydrogen atoms, while nitric acid (HNO₃) contains only one.
