(a)

Interpretation Introduction

Interpretation:

The nominal mass observed in selected ion has to be defined. Reason behind the three peaks has to be explained.

Concept Introduction:

Nominal mass in is the mass of molecular ion of most abundant isotope, where mass defect is not considered.

(b)

Interpretation Introduction

Interpretation:

The structures for the peak of mz 73 for MTBE and TAME have to be suggested. The structures for the peak of mz 87 for ETBE and TAME have to be suggested.

Concept Introduction:

Mass spectrometry is an analytical tool that determines the mass to charge ratio of molecular ion. When solid, liquid, and gaseous substances are bombarded with high energy electrons, they ionize and meanwhile fragmented. The detector detects the charge to mass ratio of the ion and produces spectrum according to their abundance.

If a high molecular weight linear polyethylene is chlorinated by inducing the substitution of chlorine atoms by hydrogen, if 5% of all hydrogen atoms are replaced, what approximate percentage of chlorine by weight would the product have?
O Macmillan Learning Chemistry: Fundamentals and Principles Davidson presented by Macmillan Learning Poly(ethylene terephthalate), known as PET or industrially as Dacron, is a polyester synthesized through a condensation reaction between two bifunctional monomers. The monomers, ethylene glycol and terepthalic acid, are given. Add bonds and remove atoms as necessary to show the structure of a two repeat unit portion of a longer polymer chain of PET. You may need to zoom out to see the complete structure of all four monomer units. Select Draw / || | C H 0 3 © Templates More ° ° ° || C CC - OH HO OH HOC - C Erase CC OH HO C C 〃 C H₂ Q2Q
