Chapter 16, Problem 46P
Interpretation Introduction

Interpretation:

The reason for the involvement of only one nitrogen, out of the three available, in semicarbazone formation, is to be explained.

Concept introduction:

Semicarbazide is an ammonia derivative. It contains an amide functionality bonded by its carbonyl to a hydrazinyl moiety.

Semicarbazone is formed when the condensation reaction between the primary amino group of semicarbazide with the carbonyl group, results in a carbon–nitrogen double bond.

In the Friedel-Crafts alkylation of benzene, dialkylation is often a significant by-product. In the Friedel-Crafts acylation of benzene, diacylation is not a significant by-product. Which of the following is the primary reason for this difference? a. Acyl cations are more difficult to make with Lewis acids b.Unlike acyl cations, carbocations can undergo rearrangements. c.Alkyl groups activate the ring to further substitution, acyl groups deactivate it. d. Alkyl groups activate the ring to further substitution, acyl groups deactivate it

The reaction of an alkyl chloride with potassium iodide is generally carried out in acetone to maximize the amount of alkyl iodide that is formed. Why does the solvent increase the yield of alkyl iodide? (Hint: Potassium iodide is soluble in acetone, but potassium chloride is not.)
