Chapter 12, Problem 12.20P
Interpretation Introduction

(a)

Interpretation:

The peaks of 2-chloropentane at m/z=71 and m/z=70 are to be classified as an even-electron and an odd-electron peak.

Concept introduction:

In mass spectrometry, an electron is lost to form a molecular ion. Two types of fragmentation occur. A stable molecular ion decomposes slowly and a peak with large relative abundance is detected in the mass spectrometer. If the molecular ion is unstable, it decomposes into several ions.

Interpretation Introduction

(b)

Interpretation:

The stable neutral molecule which can be lost to give the odd-electron ion is to be stated.

Concept introduction:

Mass spectroscopy is used to calculate mass to charge ratio of ions. Isotopic peak is also known as (M+1) peak because it shows one unit mass more than the mass of the molecular ion because the molecule consists of different isotopes of an element.

Interpretation Introduction

(c)

Interpretation:

The mechanism for the origin of each fragment ion is to be stated.

Concept introduction:

Mass spectroscopy is used to calculate mass to charge ratio of ions. Isotopic peak is also known as (M+1) peak because it shows one unit mass more than the mass of the molecular ion because the molecule consists of different isotopes of an element.

Using the conditions of spontaneity to deduce the signs of AH and AS Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions A This reaction is always spontaneous, but proceeds slower at temperatures above 120. °C. ΔΗ is (pick one) AS is (pick one) ΔΗ is (pick one) B This reaction is spontaneous except above 117. °C. AS is (pick one) ΔΗ is (pick one) This reaction is slower below 20. °C than C above.

Calculating the pH at equivalence of a titration Try Again Your answer is incorrect. 0/5 a A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of hydrocyanic acid is 9.21. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. pH = 11.43] G 00. 18 Ar B•
