Show Answer
Answer:
Correct Answer: A
Solution:
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.
$C_2H_5 (-I)$
