# Why is Cl_2 + KI -> KCl + I_2? not a synthesis reaction?

Jan 23, 2016

Not Synthesis. It is a Single Displacement.

#### Explanation:

Synthesis reactions are defined as following:

$\text{Element " + " Element} \to C o m p o u n d$

However, single displacement reactions are defined as following:

$\text{Element " + Compound -> Compound + " Element}$

Which is the case of the reaction in question:

${\underbrace{C {l}_{2}}}_{\text{Element") + underbrace(KI)_(Compound)->underbrace(KCl)_(Compound) + underbrace(I_2)_("Element}}$

The balanced equation is:

$C {l}_{2} + 2 K I \to 2 K C l + {I}_{2}$
