Select the incorrect match.

A.pKa values < 1 → strong acids

B.pKa values between 1 and 5 → moderately strong

C.pKa values between 5 and 15 → weak acids

D.pKa values > 15 → extremely strong acids✓ Correct

Explanation

Strong acids have pKa values < 1. Acids with pKa values between 1 and 5 are considered to be moderately strong acids, weak acids have pKa values between 5 and 15 and extremely weak acids have pKa values < 15.
