The following chemical reactants produce the ester ethyl ethanoate (c4h8o2):
c2h6o + ch3cooh
what type of reaction occurs to make ethyl ethanoate?
condensation
hydrolysis
combustion
acid-base reaction

The type of reaction for the formation of ethyl ethanoate  is Condensation .

Explanation:

Condensation reaction -

The reaction in which two or more reactant combines to form a product ,along with the removal of small molecules like water , ammonia etc . , is called a condensation reaction .

Ethyl alcohol and acetic acid combines together to form ethyl ethanoate  as the ester .

This is a reaction to form a ester , from alcohol and carboxylic acid .

To make water molecule, H atom is taken from the alcohol and OH is taken from the carboxylic acid , as a result remaining structures of alcohol and acid unite with each other forming an ester .

the answer is b.) hydrogen bonds between bases.
