The bromination reactions and mechanisms are compared ... of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless ...

This causes a smoky flame. Alkenes have a functional group C=C – the part of the molecule that takes part in reactions. Alkanes, in contrast, do not have a functional group and are less reactive ...

Alkenes are volatile chemical compounds that ... but is created by chemical reactions between oxides of nitrogen and volatile organic compounds. This happens when pollutants emitted by cars ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

This module builds on students' knowledge of the common functional groups within organic molecules that are responsible for many chemical reactions including aromatic rings, alkenes and carbonyls.

Organic chemistry is perhaps one of the most dreaded courses in the premedical curriculum. Some aspiring doctors even give up on their goal of going to medical school because they are deterred by ...
