Arrange the following in correct order of nucleophilicity :- CH_(3)-O

1.	Arrange the following in correct order of nucleophilicity :- CH_(3)-O - CH_(2) - O^(oplus)(I) "" Ph - CH_(2) - O^(oplus)(II) CH_(3) - O^(oplus)(III) "" ChCH_(2) - O^(oplus)(IV)
Answer» `IV gt III gt II gt I` `I gt II gt III gt IV` `III gt IV gt II gt I` `II gt I gt IV gt III` SOLUTION :IF DONAR atom is same the nucleophiliticyt is PARALLEL to basicity
