Question

Among the following compounds/the strongest acid is

• A. $ CH\equiv CH $
• B. $ {{C}_{6}}{{H}_{6}} $
• C. $ {{C}_{2}}{{H}_{6}} $
• D. $ C{{H}_{3}}OH $

Answer 1

Answer: (D)

Acids have higher tendency to lose a proton. Among the given compound, $ C{{H}_{3}}OH $ has the highest tendency to lose a proton, hence it is the strongest acid. $ C{{H}_{3}}OH\rightleftharpoons \underset{\begin{smallmatrix} alkoxide \\ ion \end{smallmatrix}}{\mathop{C{{H}_{3}}O{{H}^{-}}}}\,+{{H}^{+}} $
