(a)
Interpretation:
Making popcorn in a microwave oven has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Exothermic reaction: Those reactions that release heat energy to the surroundings are called as exothermic reactions. The formation of
Endothermic reaction: Those reactions that absorb heat energy from the surroundings are called as endothermic reactions. The breakage of chemical bonds absorbs heat energy.

A burning match has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Boiling water has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Refer to part (a).

- Complete the following esterification reactions by drawing the line formulas of the carboxylic acid and alcohol required to form the ester shown. catalyst catalyst catalyst apricot fragrancearrow_forwardShow the saponification products of the following ester: You don't need to draw in the Na+ cation. catalyst, A catalyst, A catalyst, Aarrow_forwardWhat would happen if the carboxylic acid and alcohol groups were on the same molecule? In essence, the molecule reacts with itself. Draw the structure of the products formed in this manner using the reactants below. If two functional groups interact with one another on the same molecule, this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more) attack.
