* C3H7COOH: This is Butanoic acid (also known as butyric acid). It is a carboxylic acid with a 4-carbon chain.
* CH3OH: This is Methanol, the simplest alcohol.
* C3H7COOCH3: This is Methyl Butanoate, an ester formed by the reaction of Butanoic acid and Methanol.
* HOH: This is simply water (H2O).
The reaction:
The overall reaction is an esterification reaction:
```
C3H7COOH + CH3OH <=> C3H7COOCH3 + HOH
(Butanoic acid) + (Methanol) <=> (Methyl Butanoate) + (Water)
```
Structural formulas:
Here are the structural formulas of the involved molecules:
* Butanoic acid (C3H7COOH):
```
CH3-CH2-CH2-COOH
```
* Methanol (CH3OH):
```
CH3-OH
```
* Methyl Butanoate (C3H7COOCH3):
```
CH3-CH2-CH2-COO-CH3
```
* Water (HOH):
```
H-O-H
```
Note: The reaction is reversible, meaning it can proceed in both directions. The presence of a strong acid catalyst (like H2SO4) and removal of water can shift the equilibrium towards the formation of the ester.
