Question

give examples of an addition reaction

Answer 1

A reaction in which two or more molecules combine to form a bigger molecule is called addition reaction.

In organic chemistry, this sort of reaction takes place in unsaturated compounds where there are double or triple bonds.

An example is the reaction between ethene and bromine to produce 1,2-dibromoethane.

$C_2H_4 + Br_2 \to C_2H_4Br_2$

Another example is the addition polymerization reaction of ethene to form polyethene

$nC_2H_4 \to (-C_2H_4-)_n$
