a) Alcohol
Interpretation:
The number of isomers of the following compounds is to be determined.
Concept introduction:
Ethanol, also called alcohol, ethyl alcohol, grain alcohol and drinking alcohol, is a chemical compound, a simple alcohol with the chemical formula, C2H5OH (CnH2n+1OH). In alcohol, an ethyl group linked to a hydroxyl group and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odour. It is a psychoactive substance and is the principal type of alcohol found in alcoholic drinks.
b) Bromoalkane
Interpretation:
