The highest mass peaks in the mass spectrum of Br2 occur at m/Z 158, 160, and 162. The ratio of intensities of these peaks is approximately 1:2:1. Bromine has two stable isotopes,79Br (50.7% abundance) and 81Br (49.3% abundance). question: What molecular species gives rise to each of these peaks? (Include the mass numbers of the isotopes in your answers.)
*(iii) The reaction of ethene with aqueous potassium manganate(VII), KMNO., produces ethane-1,2-diol, CH,OHCH,OH. Data: molar mass of ethane-1,2-diol = 62 g mol In an experiment, KMNO, containing only "O reacts with ethene. Suggest how the mass spectrum of ethane-1,2-diol data could be used to decide whether the oxygen atoms in ethane-1,2-diol came from the manganate(VII) ion, water, or a combination of the two. (2)

2clar ISTRY EXAM A Chemistry student performed an experiment on the preparation and identification of an ester. He was given solutions of a carboxylic acid and an alcohol. He then prepared the ester as per laboratory instruction and identified the odour of the ester as a pear flavour. A carboxylic acid has empirical formula CH,O, and its structure is determined by using various spectroscopic techniques. (a) The mass spectrum for this carboxylic acid molecule is given below. 100- 80- 60- relative intensity 40- 20- 10 15 20 25 30 35 40 45 50 55 60 65 70 75 mass/charge (m/e) (i) State the relative molecular mass of this molecule; hence determine its molecular formula.
