Final answer:

Concentrated H2SO4 serves as a dehydrating agent in esterification reactions, the oxidation of a given structure produces 2-butanone, and foaming when palm oil is added to potash indicates saponification.


Explanation:

The function of conc. H2SO4 in the esterification of ethanoic acid and ethanol is to serve as a dehydrating agent, removing water from the reaction mixture to promote the formation of the ester.

The oxidation of CH3CH2CH2C-OH yields 2-butanone as the product.

When palm oil is added to potash and foaming is observed, the reaction that takes place is saponification, which is the hydrolysis of an ester to form soap.
