Question

Which is a product of a condensation reaction? 1. O2 2. CO2 3. H2 4. H2O

Answer 1

`H_(2)O` is a product of a condensation reaction.

Step-by-step explanation:

In a condensation reaction, two molecules are combined to produced a large molecules along with removal of a water molecule.

For an example, let's consider aldol condensation reaction.

In aldol condensation reaction, an enolate anion reacts and combines with an aldehyde or ketone molecule follwed by dehydration. In that dehydration step ,
`H_(2)O` gets removed and an unsaturated carbonyl product is formed.

Usually,
`O_(2),CO_(2) and H_(2)` are produced as a by product of a decomposition reaction.

Answer 2

The correct answer is H2O, it is a product of a condensation reaction. It is a type of chemical reaction where two molecules combine to form a larger molecule together with a loss of a small molecule. Usually, this small molecule is water.
