NEET 2017 · ChemistryPrevious Year Question

Which one is the correct order of acidity?

Answer: (B) $CH \equiv CH > CH X_{3} - C \equiv CH > CH X_{2} = CH X_{2} > CH X_{3} - CH X_{3}$ .

A. $CH X_{2} = CH X_{2} > CH X_{3} - CH = CH X_{2} > CH X_{3} - C \equiv CH > CH \equiv CH$
B. $CH \equiv CH > CH X_{3} - C \equiv CH > CH X_{2} = CH X_{2} > CH X_{3} - CH X_{3}$ ✓
C. $CH \equiv CH > CH X_{2} = CH X_{2} > CH X_{3} - C \equiv CH > CH X_{3} - CH X_{3}$
D. $CH X_{3} - CH X_{3} > CH X_{2} = CH X_{2} > CH X_{3} - C \equiv CH > CH \equiv CH$

Correct Answer

(B) $CH \equiv CH > CH X_{3} - C \equiv CH > CH X_{2} = CH X_{2} > CH X_{3} - CH X_{3}$
