The group which leaves from the subtrate in a nucleophilic substitution reaction is called?
Correct answer: A. Leaving group
- A. Leaving group
- B. Electrophile
- C. Substrate
- D. Weak nucleophile
Explanation
Option A is correct as groups or particles that leave the main by being substituted are called "leaving groups".Option B is incorrect as "electrophiles" are particles which are attracted and attack negatively charged molecules.Option C is incorrect as the "substrate" is the main molecule from which the leaving group has left.Option D is incorrect as "nucleophiles" are particles which are attracted to positively charged molecules.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
