List all the clues that you can gather on the composition of the molecule whose spectrum is shown below:
Homework Answers
M and M+2 peak at 184 and 186 m/z in 1:1 intensity show the presence of bromine atom
Peak at 169 and 171 due to the loss of methyl group (CH3) from the molecule
Peak at 77 m/z is due to presence of phenyl moiety
Peak at 105 m/z might to the presence of ethyl benzene moiety
Therefore structure of the compound might be 1-bromo-4-ethyl benzene

Studies have shown that exercising can help prevent heart disease. Within reasonable limits, the more you exercise, the less risk you have of suffering from heart disease. One way in which exercise reduces your risk is by reducing serum cholesterol. The more you exercise, the lower your cholesterol concentration. It has recently been shown that the amount of time you spend watching TV, an indicator of a sedentary lifestyle, might be a good predictor of heart disease; that is, the...
