The line bond structures are used to indicate covalent bonds by using lines to represent two electrons shared between two atoms. The line bond structure of chloroform with C as the central atom is as shown:

Structure of chloroform

To represent the three-dimensional geometry of a molecule, we need to use

* a solid line to represent a bond in the plane of the page.

*A dashed line to represent a bond going back below the plane of the page, and

*A wedged line to represent a bond above the plane of the page.

To represent tetrahedral geometry around C, draw two bonds using solid lines, one bond using a dashed line, and one bond using a wedged line.

The three-dimensional structure of chloroform is represented as:
