Draw structures corresponding to the following IUPAC names: (c) 3-Bromo-3-ethylpentane.

IUPAC rules used for naming of Alkyl halides

• Select longest carbon chain, it is the parent chain;
• Longest chain must contain double or triple bond, if present;
• Number the alkyl or halo substituent carbon i.e. it should possess lowest number in the parent chain;
• Assign a number to each substituent;
• Write the name of substituent’s in alphabetical order while naming;

(c) As the chemical name indicates, that the given alkyl halide is pentane, which means it has five carbon atoms in the parent chain.

It is having two substituents i.e. one bromo group and one ethyl group, so they will be assigned position alphabetically and numbering is done at the end nearer the substituents.

Both the substituents are present on number 3 carbon. Thus, the given compound has following structure:
