Question

What is the name of this molecule?

Answer 1

The name of the compound is 6,6-dichlorobicyclo[3.1.0]hexane.

Explanation:

The rules for naming bicyclic hydrocarbons are.

1. The root name depends the total number of carbon atoms in the
rings (6 = hexane).

2. The root name is preceded by the prefix "bicyclo-" (bicyclohexane).

3. Numbers indicate the length if each chain between the bridgehead
atoms (3, 1, and 0).

4. The numbers are placed in brackets, listed in decreasing order of size, and separated by periods ([3.1.0]).

5. These are inserted before the root name (bicyclo[3.1.0]hexane).

6. The rings are numbered from a bridgehead atom along the longer path to the other bridgehead atom, then along the smaller path back to the first bridgehead.

Thus, the name of the compound becomes 6,6-dichlorobicyclo[3.1.0]hexane.
