Mainly the product formed in this type of reaction is an alcohol.

In Combustion reaction, organic molecules breaks down into simpler molecules of carbon-dioxide and water.

In esterfication reaction ,condensation of one molecule of carboxylic acid and alcohol molecules takes place with release of small molecule of water.

In polymerization is the reaction in which same molecule of a compound  combines number of times to form a polymer is knows as polymerization.
