Question
Chapter 14, Problem 14.44SP
Interpretation Introduction
Interpretation: The information regarding the desired product using the spectroscopic characterisation is given. The structure corresponding to the product and the explanation corresponding to the observed spectra is to be identified.
Concept introduction: In IR spectroscopy, the vibration of atoms is measured. Lighter atoms and stronger bonds vibrate at a high wave number (stretching frequency).
In NMR spectroscopy, local magnetic field is observed around the atomic nuclei.
To determine: The structure corresponding to the product and the explanation corresponding to the observed spectra.

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?
Steps and explanations. Also provide, if possible, ways to adress this kind of problems in general.
