What can be said about the shape of the infrared stretch of the o-h functional group in a carboxylic acid. pick the best answers. a. weak?
b. strong?
c. very broad?
d. comes to a double point?
e. sharp?

Strong (b)

Explanation:

INFRARED ACTIVE BONDS

Not all covalent bonds display bands in the IR spectrum. Only polar bonds do so. These are referred to as IR active.

The intensity of the bands depends on the magnitude of the dipole moment associated with the bond in question:

Strongly polar bonds such as carbonyl groups (C=0) produce strong bands.

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.
