Question

hiii friends!
please tell me about nucleophilicity order of ch3-, nh2-,oh-, F- with reason.
it's urgent....

Answer 1

Nucleophilicity is the tendency of the atom to donate electrons.

•Negative charge is more stable on more electronegative atom.

•Among NH2– and CH3– ,nucleophilicity of CH3– is more since negative charge on nitrogen atom is more stable than carbon ,so carbon will be more willing to donate electrons.Nucleophilicity is the tendency of the atom to donate electrons.


hope its helpful

Answer 2

Answer:

The nucleophilicities of CH3-, NH2-, OH-, and F- decrease in the order CH3– > NH2– > OH– > F-

Explanation:

How can you tell if something is nucleophilic?

In a substitution reaction, nucleophilicity refers to a nucleophile's capacity to displace a leaving group. The trend in nucleophilicity and basicity in acetone and other polar aprotic solvents is the same. Fluoride is the strongest base and the strongest nucleophile. As the density of the negative charge grows, so does nucleophilicity. The conjugate base is always a better nucleophile than a neutral molecule because an anion is always a better nucleophile than a neutral molecule. Because it is unwilling to exchange its electrons, a highly electronegative atom is a poor nucleophile.

Thus, the term "nucleophile" refers to compounds that transfer electron pairs to electrophiles in order to establish chemical bonds with them.
