Chapter 12: Q-21-21-4P (page 354)

Rank the compounds in each of the following sets in order of their expected reactivity toward nucleophilic acyl substitution:

Short Answer

Expert verified

The order of reactivity towards nucleophilic acyl substitution:

(a)

(b)

Step by step solution

01

Nucleophilic acyl substitution

The organic group that is shown in image is the acyl group.

When acyl group reacts with a nuclephile, the leaving group in them is replaced by the nuclephile.

02

Subpart (a)

The kinetic factor which rate the reaction is the leaving group attached to acyl carbon. The condition for the reaction seems identical, faster the leaving list will gives the reaction faster.

The order of reactivity can be denoted as,

03

Subpart (b)

The compound order is based on the expected reactivity rate.

The reaction rate will be increased for the weaker base. The order of nucleophile acyl substitution can be denoted as,

Most popular questions from this chapter

Rank the double bonds below in terms of increasing stability:

How might you use IR spectroscopy to distinguish between the followingpairs of isomers?

(a) CH3 CH2 OH and CH3 OCH3

(b) Cyclohexane and 1 - hexene

(c) CH3 CH2 CO2 H and HOCH2 CH2 CHO

Question: Halogenated compounds are particularly easy to identify by their mass

spectra because both chlorine and bromine occur naturally as mixtures

of two abundant isotopes. Recall that chlorine occurs as 35Cl (75.8%)

and 37C (24.2%); and bromine occurs as 79Br (50.7%) and 81Br (49.3%).

At what masses do the molecular ions occur for the following formulas?

What are the relative percentages of each molecular ion?

(a)Bromomethane, CH3Br

(b)1-Chlorohexane, C6H13Cl

Question: 2-Methylpentane (C6H14)has the mass spectrum shown. Which peak

represents? Which is the base peak? Propose structures for fragment

ions of m/z=71, 57, 43, and 29. Why does the base peak have the mass it does?

Question: Where might the following compounds have IR absorptions?
