Question

Which of the following is not a base? A: NH3 B. NaOH C. H3C6H5O7 D. KOH

Answer 1

I think that C is the answer.....

Answer 2

Answer: Option (C) is the correct answer.

Explanation:

A base is a substance or specie that contains a lone pair of electron or a hydroxyl group, that is, OH group.

For example, $NH_{3}$, NaOH, and KOH are all bases.

But $H_{3}C_{6}H_{5}O_{7}$ is not a base because there is no lone pair of electron and no hydroxyl group.

Thus, we can conclude that out of the given options $H_{3}C_{6}H_{5}O_{7}$ is not a base.
