How long did the conversion of benzoyl chloride to n, n-diisopropylbenzamide take?

It was first prepared by treatment of benzaldehyde with chlorine. the method was early for production of benzoyl chloride involved chlorination of benzyl alcohol.

Benzoyl chloride was made from benzotrichloride using either water or benzoic acid.

CHCCl + CHCOH → 2 CHCOCl + HCl As with other acyl chlorides, it can be generated from the parent acid and other chlorinating agents phosphorus pentachloride or thionyl chloride.

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.
