Ques: Q: Which class of acids acetic acid (ch 3 cooh) belongs to? Read this paragraph and choose the correct option from the provided answers: Not all hydrogen atoms in molecular compounds are ionizable. In methane (CH 4 ), the hydrogen atoms are covalently bonded to carbon in bonds that are only slightly polar. The hydrogen atoms are not capable of ionizing and methane has no acidic properties. Acetic acid (CH 3 COOH) belongs to a class of acids called organic acids. There are four hydrogen atoms in the molecule, but only the one hydrogen that is bonded to an oxygen atom is ionizable. Choices: - anorganic acids - strong acids - common acids - organic acids A:
Ans: organic acids
