MHT CET Chemistry Question (2026) — Solution
Options
- A. Cl ^-
- B. CH _3 COO ^-
- C. NO _3^-
- D. HSO _4^-
Answer
B. CH _3 COO ^-
Step-by-step solution
According to the Bronsted-Lowry theory, a stronger base has a weaker conjugate acid. The conjugate acids of the given bases are: Cl ^- HCl (strong acid) CH _3 COO ^- CH _3 COOH (weak acid) NO _3^- HNO _3 (strong acid) HSO _4^- H _2 SO _4 (strong acid) Since CH _3 COOH is the weakest acid among the given conjugate acids, its conjugate base CH _3 COO ^- is the strongest base. Answer: CH _3 COO ^-
