NEET Solved Paper 2017 Question 13
Question: Which one is the correct order of acidity?
Options:
A) $ CH _3=CH _3>CH _2=CH _2>CH _3-C=CH>CH=CH $
B) $ CH _2=CH _2>CH _3-CH=CH _2>CH _3-C\equiv CH> $ $ CH\equiv CH $
C) $ CH\equiv CH>CH _3-C\equiv CH>CH _2=CH _2>CH _3-CH _3 $
D) $ CH\equiv CH>CH _2=CH _2>CH _3-C\equiv CH>CH _3-CH _3 $
Show Answer
Answer:
Correct Answer: D
Solution:
- Correct order is $ \underset{\begin{smallmatrix} (Two,acidic \\ hydrogens) \end{smallmatrix}}{\mathop{H-C\equiv C-H>}},\underset{\begin{smallmatrix} (One,acidic \\ hydrogen) \end{smallmatrix}}{\mathop{H _3C-C\equiv C-H>}},H _2C=CH _2 $ $ >CH _3-CH _3 $
