Write the names and molecular formula of two organic compounds having functional group suffixed as '-oic acid' with the help of a balanced equations, exaplain what happens when any of them reacts with sodium hydroxide.

Explanation

The organic compounds with functional group- oic acid are known as carboxylic acids or alkanoic acids. These are represented by general formula RCOOH (where R may be H atom or alkyl group). For example,
`underset("Methanoic acid")(H-overset(O)overset(||)(C)-O-H)" "underset("Ethanoic acid")(H-underset(H)underset(|)overset(H)overset(|)(C)-overset(O)overset(||)(C)-O-H)`
On reacting a carboxylic acid with sodium hydroxide (NaOH), corresponding sodium salt and water are formed.
the reaction is known as neutralisation.
`underset("Methanoic acid")(HCOOH)+NaOHtounderset("Sod. methanoate")(HCOONa)+H_(2)O`
