Draw structures corresponding to the following IUPAC names: (e) 4-sec-Butyl-2-chlorononane.

Alkyl halides are also known as haloalkanes or halogenoalkanes. They contains one or more halogen substituents i.e. –Br, -Cl,-I,-F.

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;

It is having two substituents i.e one sec-butyl group and one chloro group, so they will be assigned position alphabetically.

The chloro group is positioned on number 2 and sec-butyl on number 4 carbon. The numbering is done from that end of the parent chain, from where the substituents possess lowest number. Thus, the given compound has following structure:
