Explain Vinylic substitution​

Answer 1

Answer:

Nucleophilic vinylic substitutions are closely related to nucleophilic aromatic substitutions, as in both the leaving group leaves from an unsaturated carbon atom. ... The stereochemistry of the substitution depends on the configuration of the substrates and on the specific route involved.

may this helps

Answer 2

Nucleophilic vinyl substitutions are closely linked to nucleophilic aromatic substitutions.

• The vinyl substitutions and nucleophilic aromatic substitutions both leave from an unsaturated carbon atom in the leaving community.
• The substitution stereochemistry depends on the substrate configuration and the particular route involved.
• However, nucleophilic replacement of a halogen atom directly attached to a double bond, as in the vinyl and phenyl halides, is not readily feasible
