Condensation Reaction:

R₁-C-OH + H-O-R₂ ⇌ R₁-C-O-R₂ + H₂O

O
```
Explanation:
* Reactants: Two molecules, one with a hydroxyl group (-OH) and another with a hydrogen atom (H) on a functional group.
* Product: A larger molecule formed by joining the two reactants, with the removal of a water molecule (H₂O).
* Mechanism: The hydroxyl group loses its hydrogen, and the other molecule loses the hydrogen from its functional group. The two molecules then combine to form a larger molecule.
Hydrolysis Reaction:

R₁-C-O-R₂ + H₂O ⇌ R₁-C-OH + H-O-R₂
||
O
```
Explanation:
* Reactant: A larger molecule with a functional group, and water (H₂O).
* Products: Two smaller molecules, one with a hydroxyl group (-OH) and another with a hydrogen atom (H) on a functional group.
* Mechanism: The water molecule breaks the bond between the two parts of the larger molecule, adding a hydrogen atom to one molecule and a hydroxyl group to the other.
Key Points:
* Condensation reactions build larger molecules from smaller ones by removing water.
* Hydrolysis reactions break down larger molecules into smaller ones by adding water.
* These reactions are important for many biological processes, including the formation of polymers like carbohydrates, proteins, and nucleic acids.
Note:
This is a simplified illustration of condensation and hydrolysis reactions. The actual reactions can be more complex depending on the specific molecules involved.
