Question
Chemistry Question on reaction mechanism
The increasing order of nucleophilicity of the following nucleophiles is : (a) CH3CO2⊖ (b) H2O (c) CH3SO3⊖ (d) O⊖H
A
(b)<(c)<(a)<(d)
B
(a)<(d)<(c)<(b)
C
(d)<(a)<(c)<(b)
D
(b)<(c)<(d)<(a)
Answer
(b)<(c)<(a)<(d)
Explanation
Solution
ione pair donating tendency on oxygen is reduced, nucleophilicity reduced b < c < a < d
