A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Nucleophiles are those substances which can donate a pair of electrons. These can be neutral or negative. The nucleophilic power depends on the tendency of species to donate electrons. This is more, when an electron pushing group (+ I group) is present. Among the alkyl groups, those having higher number of C -atoms will push more, hence ethyl > methyl.
C 2 H 5 >> S – H, CH 3 >> 
– O – , CH 3 >> NH 2 ,
(+I) (+I) (+I)
CH 5 + CH 2
(–I)
