Interpretation:

The IUPAC name of the molecule shown is to be written.

Concept introduction:

The root name of an alkane is determined on the basis of the longest chain of carbons. If the compound also contains a ring with more carbon atoms, then the root name is determined on the basis of number of the ring carbons, as a cycloalkane. If there are multiple substituents on the ring, the ring carbon with the greatest number of substituents is numbered 1. The rest of the ring carbons are then numbered so that the next substituent gets the lowest number. The substituents are named alphabetically. Their positions are indicated by numbers preceding the names. The numbers and names of substituents are separated by dashes. If the same substituent occurs more than once, the number is indicated by a prefix di-, tri- etc., with the positions of both indicated by appropriate numbers.
