Since esters are cleaved on hydrolysis, the molecular weight of the acid derived from an ester is always lower than the molecules weight of the ester. however, esters are equally liquids while carboxylic acids are usually solids. suggest reasons for this observation and explain.

1 is the answer to this problem

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
