Heating a carboxylic acid with a primary amine forms water along with what organic product? oa) a secondary amide ob) a primary amide oc) an ester od) a tertiary amide

A) secondary amide

Explanation:

When carboxylic acid reacts with a primary amine, a condensation reaction takes place with the elimination of a water molecule .

For example, ethanol reacts with methylamine which is a primary amine gives N-Methylacetamide and a water molecule as:

The bond formed which is

  O

   ||

-- C  ---NH ---

is known as secondary amide group as only one hydrogen is attached to nitrogen atom in the amide bond.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
