Question

Which one of the following has maximum nucleophilicity ?

• A. $\stackrel { \ominus } { \mathrm { C } } \mathrm { H } _ { 3 }$
• B.
• C.
• D.

Answer 1

Answer: (A)

$\stackrel { \ominus } { \mathrm { C } } \mathrm { H } _ { 3 }$

Answer 2

Nucleophilicity$\propto$ $\frac{1}{electronegativity}$ (in a period). Nucleophilicity $\propto$ $\frac{1}{electronegativity}$ (in a period).
