What would be the bond line notation for 1-Ethyl-4-isopropylcyclooctane?

                  The bond line notation of 1-Ethyl-4-isopropylcyclooctane is attached below in Figure 1.

Explanation:

                    In organic chemistry the structures of organic compounds are represented in many ways.

                 i)  Condensed Formula: In this type of representation the structure of organic compound is represented in a text based manner. Each carbon atom is shown separately with other atoms attached to it.

                Example: Butyric Acid is represented as CH₃CH₂CH₂COOH  

                 ii)  Displayed Formula: In this representation all atoms are shown along with the bonds joining them.

                Example: Butyric Acid is represented as shown in attached figure 2.

                 iii)  Structural Formula: This formula is same as displayed formula but in this method carbon and hydrogen are simplified to condensed form and the bonds between carbon atoms are shown.

                Example: Butyric Acid is represented as shown in attached figure 2.

                 iii)  Skeletal Formula or Bond Line Notation method: In this method most of the hydrogen atoms are not shown. Each line ending and vertices represents carbon atoms. This is the easiest and common way of drawing organic compounds.

                Example: Butyric Acid is represented as shown in attached figure 2.
