WHY THE IONIC REACTIONS ARE FASTER?

How are reactions related to chemical bonds?

The type of bond has a great effect on the rate of reaction or speed of reaction.

Here we are going to discuss why and how it happens,

First of all in case of ionic compounds:-

Lets take example of Sodium hydroxide and Hydrochloric acid

NaOH (aq) + HCl (aq) →  NaCl + H₂O

Now lets see in depth about ions of reactants

Here the ions are already formed in the solution only rearrangement is required. And some times the reaction is completed in some seconds only.

so in the above case we have seen the ions are just to be rearranged.

Now in case of covalent compounds

Lets take an example of reaction between Iodomethane and Potassium hydroxide

CH₃I + KOH → KI + CH­₃OH

Here in this reaction it took more time as it required to break the old bonds and to form the new bonds.

As shown here

Conclusion :-

So at last we can conclude that the ionic reactions are faster because they involve simply the rearrangement of ions , as the ions are already released in solution.

In case of covalent old bond breaking takes a lot of time and also new bond formation is also time consuming so these reactions are slow.
