Question

Structure and synthesis of nucleophilic substitution reaction

Answer 1

Answer:

nucleophilic substitution reactions invove halogenoalkane

Explanation:

substitution with NaOH aq gives an alcohol

the nucleophile is OH- ion.

reaction with CH3CH2Br gives CH3CH2OH and NaBr

substitution with KCN along with ethanol gives a nitrile

the nucleophile is CN-

reaction with CH3CH2Br gives CH3CH2CN and KBr

substitution with ammonia along with ethanol gives a nitrile

nuclephile is NH3

reaction with CH3CH2Br gives CH3CH2NH2

if CH3CH2Br is in excess there is secondary amine [CH3CH2]2 NH

tertiary amine and so on

Answer 2

Explanation:

The most general form of the reaction may be given as the following: Nuc: + R-LG → R-Nuc + LG: The electron pair (:) from the nucleophile (Nuc) attacks the substrate (R-LG) and bonds with it. ... Nucleophilic substitution reactions are common in organic chemistry (especially introductory organic chemistry
