Uptake of methyl bromide and pathways for excretion of (14)C were investigated in male Fischer 344 rats after nose only inhalation of 50, 300, 5700, or 10,400 nmoles (1.6 to 310 ppm) of (14)C methyl bromide/l of air for 6 hr. Fractional uptake of methyl bromide decreased at the highest concentrations, with 37 and 27% of the inhaled methyl ...

Figure 7.1a Substitution reaction. In this reaction, the Br in the reactant methylbromide (CH 3 Br) is replaced by the OH group, and the methanol (CH 3 OH) is produced as the major product, together with bromide Br-, the side product. It is easy to understand that this is a substitution reaction, because Br is substituted by OH.

Alkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown color to give a colorless liquid. In the case of the reaction with ethene, 1,2-dibromoethane …
