Question

Write the formula for the conjugate base acid of hexanoic acid

Answer 1

The conjugate base of hexanoic acid is C6H11O2−, formed by the removal of a hydrogen ion from the acid.

Step-by-step explanation:

The conjugate base of an acid is formed by the removal of a hydrogen ion (H+) from the acid molecule. For hexanoic acid, which has the chemical formula C6H12O2, the formula for its conjugate base would be C6H11O2−. This is because hexanoic acid (C6H12O2) would lose an H+ ion to become the conjugate base hexanoate (C6H11O2−).

Examples of other acid-base pairs include water (H2O) and hydroxide ion (OH−), trimethylamine ((CH3)3N) and its protonated form ((CH3)3NH+), and sulfuric acid (H2SO4) with its conjugate base hydrogen sulfate (HSO4−).

Answer 2

Step-by-step explanation:

Chemical formula of hexanoic acid is
`CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)COOH`. According to Bronsted-Lowry, acid upon dissociation gives conjugate base and base upon dissociation gives conjugate acid.

Hexanoic acid will dissociates as follows.

`CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)COOH \rightarrow CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)COO^(-) + H^(+)`

Therefore, we can conclude that conjugate acid of hexanoic acid is
`CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)COO^(-)`
