Interpretation Introduction

(a)

Interpretation:

The fragmentation mechanisms for the observation of strong peak at m/z=74 in EI mass spectrum of 2-methylpentanoicacid is to be stated.

Concept introduction:

The EI mass spectrum is one of the types of mass spectrum in which an organic compound is vaporized and is analyzed by the bombardment with high energy electrons. When high energy passes by the molecule, it ejects an electron. The molecule results in the formation of the radical cation. This radical cation is then fragmented into small pieces. The rate of fragmentation depends upon the stability of the radical cation.

Interpretation Introduction

(b)

Interpretation:

The fragmentation mechanisms for the observation of strong peak at m/z=105 and

m/z=77 in EI mass spectrum of benzoic acid is to be stated.

Concept introduction:

The EI mass spectrum is one of the types of mass spectrum in which an organic compound is vaporized and is analyzed by the bombardment with high energy electrons. When high energy passes by the molecule it ejects an electron the molecules results in the formation of the radical cation. This radical cation is then fragmented into small pieces and rate of fragmentation depends upon the stability of the radical cation.

110. Compare the pressures given by (a) the ideal gas law, (b) the van der Waals equation, and (c) the Redlic-Kwong equation for propane at 400 K and p = 10.62 mol dm³. The van der Waals parameters for propane are a = 9.3919 dm6 bar mol-2 and b = 0.090494 dm³ mol−1. The Redlich-Kwong parameters are A = 183.02 dm bar mol-2 and B = 0.062723 dm³ mol-1. The experimental value is 400 bar.
Research in surface science is carried out using stainless steel ultra-high vacuum chambers with pressures as low as 10-12 torr.  How many molecules are there in a 1.00 cm3 volume at this pressure and at a temperature of 300 K?  For comparison, calculate the number of molecules in a 1.00 cm3 volume at atmospheric pressure and room temperature.  In outer space the pressure is approximately 1.3 x 10-11 Pa and the temperature is approximately 2.7 K (determined using the blackbody radiation of the universe).  How many molecules would you expect find in 1.00 cm3 of outer space?
