Question

The organic reaction: $C_2{H}_6+C{l}_2\to HCl+C_2{H}_{5}Cl$, is best described as :

• A. a substitution reaction
• B. an addition reaction
• C. an esterification
• D. a dehydration synthesis
• E. a fermentation

Answer 1

The correct option is A a substitution reaction

$C_2{H}_6+C{l}_2\to HCl+C_2{H}_{5}Cl$
As here the H atom from $C_2{H}_5-H$ is substituted by $Cl$ of $HCl$, hence, this is substituted reaction.
Substitution reaction is a class of chemical reactions in which an atom, ion or group of atoms or ions in a molecule is replaced by another atom, ion or group.
