Question

Rank the following acids from strongest to weakest: 1. HI 2. CH3NH2 3. F-CH2-COOH 4. CH3OH 5. CH3COOH

Answer 1

Answer #1

Strong acid has large Ka value or small pKa value.

The pKa values of given compounds as follows:

HI ------> -10

CH3NH2 ------> between 30-40

F-CH2-COOH -----> 2.66

CH3OH -------> 17

CH3COOH ------> 4.76

Hence, the Decreasing order of acid strength is as follows:

Strongest HI < F-CH2-COOH < CH3-COOH < CH3OH < CH3NH2 weakest acid
