Question

What are the differences between hydration, hydrolysis and condensation ?

Answer 1

Hint: In this we have to differentiate between the hydration, hydrolysis and condensation on the basis of their physical and chemical properties through the definition, examples , presence of water and double or triple bonds, whether exothermic or endothermic etc. Now you can easily answer the statement.

Complete answer:
We will differentiate between the three i.e. the hydration, hydrolysis and condensation in the tabular form because it's an easy way to understand them and learn them.
Their difference is as below

Sr No.	Property	Hydration	Hydrolysis	Condensation
1.	Definition	The reaction in which the water reacts with alkene or alkyne to form alcohol is known as hydration reaction.	The reaction in which the breakage of bond occurs due to the addition of water is known as hydrolysis reaction.	The reaction in which two or more substances react together to form one product along with the release of some side products is known as the condensation reaction.
2.	Presence of unsaturation	It cannot occur in the absence of unsaturated compounds.	It doesn’t require any double or triple bond to undergo the reaction.	It doesn’t require any double or triple bond to undergo the reaction.
3.	Presence of water.	Water is necessary for the reaction to occur.	Water is necessary for the reaction to occur.	Water is not necessary for the reaction to occur.
4.	Exothermic/endothermic	It is exothermic in nature.	It can be either exothermic or endothermic in nature.	It is exothermic in nature.
5.	Examples	${{C}_{2}}{{H}_{4}}\xrightarrow{{{H}_{2}}O}{{C}_{2}}{{H}_{5}}OH$	${{H}_{2}}S{{O}_{4}}\xrightarrow{{{H}_{2}}O}{{H}_{3}}{{O}^{+}}+HSO_{4}^{-}$	$\begin{align} & C{{H}_{3}}COOH+{{C}_{2}}{{H}_{5}}OH\xrightarrow[-{{H}_{2}}O]{} \\ & C{{H}_{3}}COO{{C}_{2}}{{H}_{5}} \\ \end{align}$

So, it’s easy to distinguish the hydration, hydrolysis and condensation in the tabular form rather than in the paragraph form.

Note:
Don’t get confused in the exothermic and endothermic reactions. Exothermic reactions are those reactions in which energy is released in the form of heat or light whereas on the other hand, in case of the endothermic reactions, energy is taken in the form of heat and light.
