Organic Compounds Containing Halogens Question 191
Question: $ CH_3Br+N{u^{-}}\xrightarrow{{}}CH_3-Nu+B{r^{-}} $ The decreasing order of the rate of the above reaction with nucleophiles $ ( N{u^{-}} ) $ A to D is $ [N{u^{-}}=(A)Ph{O^{-}},(B)Ac{O^{-}},(C)H{O^{-}},(D)CH_3{O^{-}}] $
Options:
A) $ A>B>C>D $
B) $ B>D>C>A $
C) $ ~D>C>A>B $
D) $ D>C>B>A $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] The acid character follows the order: $ CH_3COOH>C_6H_5OH>H_2O>CH_3OH $ The basic character will follow the order $ CH_3CO{O^{-}}<C_6H_5{O^{-}}<O{H^{-}}<CH_3{O^{-}} $ The stronger the acid, the weaker the conjugate base formed.
