Question

Match the following:

List-I (Compound)	List-II (pKa)
A) p-Nitrophenol	I) 15.9
B) Phenol	II) 7.1
C) Ethanol	III) 10.0
D) p-Cresol	IV) 10.2

• A. A-II, B-V, C-I, D-III
• B. A-II, B-III, C-I, D-IV
• C. A-V, B-II, C-I, D-III
• D. A-IV, B-III, C-I, D-V

Hint:

pKa values help identify the acidity of compounds. The lower the pKa, the stronger the acid.

Answer 1
