Type: MCQ-numerical-Hard-Class 12
Based on the pKa values provided, by what factor is phenol more acidic than ethanol?
A
10,000
B
1,000,000
C
100,000
D
10,000,000
Correct Answer
Option B
Detailed Explanation
The pKa of phenol is 10.0 and that of ethanol is 15.9. The acidity difference is calculated as 10^(15.9 - 10.0) = 1,000,000 times, indicating phenol is a million times more acidic than ethanol.
