Order nucleophilicity
`(i)OH-" "(ii)HS^(-)" "(iii)Ph-O^(-)" "(iv)C_(2)H_(5)-O^(-)`

A

`I gt ii gt iiigt iv`

B

`ii gt iv gt I gt iii`

C

`ii gt iii gt I gt iv`

D

`iii gt iv gt I gt ii`

Text Solution

Verified by Experts

The correct Answer is:
B
Order of nucleophilicity
`OH^(-), HS^(-), Ph-O^(-), C_(2)H_(5)O^(-)=HS^(-)gt C_(2)H_(5)O^(-)gt OH^(-)gt Ph -O^(-)`
On increasing delocalization of `e^(-)` nucleophilicity decrease
