Substitution nucleophilic biomolecular reaction is a one-step reaction and doesn’t involve any intermediate.It is a type of reaction where one side the bond breaks and formation takes place on the other side.

(a) When bromoacetic acid reacts with excess NH_3,its ammonium salt

Formation of ammonium salt

(b) When diethyl acetamidomalonate is treated with (CH₃)₂ CHCl and undergoes heat and hydrolysis, valine is formed.

Formation of valine

(c) When 2-methyl butanol is treated with NH₄Cl, NaCN and undergoes hydrolysis isoleucine is formed.

Formation of isoleucine

(d) When diethyl acetamidomalonate is treated with NaOEt, BrCH₂CO₂Et and undergoes hydrolysis and heat,2-aminobutanedioic acids are formed.

Formation of 2-aminobutanedioic acid
