Draw the structure of 4-chlorophthalic acid in the window below.

The Molecular formula of the 4-chloropthalic acid:

Explanation:

In 4-chloropthalic acid the main the skeleton in the molecule is benzene ring.

In benzoic acid the one more carboxylic group is present at ortho position and one chloro group is present at para position of the ring.

The structure of the 4-chloropthalic acid is given in an image.

the increase of protons   hope this

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.
