Alkenes (A Level Chemistry Revision Notes)

Alkenes

Alkenes are unsaturated hydrocarbons containing carbon-carbon double bonds. The carbon-carbon double bond is the functional group for alkenes, known as ethylenic linkage. The general formula of an alkene is CnH2n, where n is the integer number. Alkenes consist of two … Read more

Isomerism (A Level Chemistry Revision Notes)

Isomerism

Isomerism occurs when many substances have the same chemical formula but different chemical structures. The term “isomer” comes from the Greek words “isos” and “meros,” both of which signify “equal parts.” In the year 1830, the Swedish chemist Jacob Berzelius … Read more

Azo Compounds (A Level Chemistry Revision Notes)

Azo compounds

Azo compounds are the compounds of both natural and manufactured chemicals that contain at least one azo group (N=N) in their structure. The atomic groups connected to the nitrogen atoms might be of any organic class, but the commercially relevant azo … Read more

Amide (AS and A Level Chemistry)

Amides

Amides are carboxylic acid derivatives of amines. A carboxylic acid has the -COOH group, and in amide, the -OH group of the carboxylic acid is substituted by the -NH2 (amino) group, resulting in the -CONH2 group. They are therefore compounds … Read more
