Chapter 10.SE, Problem 43AP
Interpretation Introduction

Interpretation:

Given that addition of HBr to a double bond with an ether substituent occurs regiospecifically to give a product in which the –Br and –OR are bonded to the same carbon. Two carbocation intermediates possible in this electrophilic addition reaction are to be drawn. The formation of the product is to be explained using the concept of resonance.

Concept introduction:

In electrophilic addition reactions the first step involves the abstraction of the positively polarized hydrogen of H-Br by the π electrons of the double bond to yield a more stable carbonium ion eliminating the bromine as bromide ion. In the second step the bromide ion attacks the carbocation to yield the product.

To draw:

The structures of the two carbocation intermediates possible in the electrophilic addition of HBr into methoxy cyclohexene.

To explain:

The formation of the regiospecific product using the concept of resonance.

Given the reaction R+ Q → P, indicate (A). the rate law with respect to P: (B). the rate law with respect to R: (C). the rate law with respect to Q: d[P] dt d[R] dt d[Q] dt
The reaction for obtaining NO2 from NO and O2 has the rate equation: v = k[NO]2[O2]. Indicate which of the following options is correct.(A). This rate equation is inconsistent with the reaction consisting of a single trimolecular step.(B). Since the overall order is 3, the reaction must necessarily have some trimolecular step in its mechanism.(C). A two-step mechanism:  1) NO + NO ⇄ N2O2 (fast);   2) N2O2 + O2 → NO2 + NO2 (slow).(D). The mechanism must necessarily consist of three unimolecular elementary steps with very similar rate constants.
a. What is the eluent used in the column chromatography here (a “silica plug filtration” is essentially a very short column)? b. The spectroscopy of compound 5b is described in the second half of this excerpt, including 1H-NMR and 13C-NMR (which you will learn about in CHEM 2412L), MS (which you will learn about later in CHEM 2411L) and IR. One of the IR signals is at 3530 cm-1. What functional group does this indicate might be present in compound 5b?
