Question

Correct arrangement of the following nucleophiles in the order of their nucleophilic strength is

• A. C6H5O– < CH3O–< CH3COO–< OH–
• B. CH3COO–< C6H5O–< CH3O–< OH–
• C. C6H5O–< CH3COO–< CH3O–< OH–
• D. CH3COO–< C6H5O–< OH–< CH3O–

Answer 1

Answer: (D)

CH3COO–< C6H5O–< OH–< CH3O–

Answer 2

As increases delocalisation of negative charge nucleophilicity decreases.
