This is a shorthand representation of an organic molecule with lines which represents its molecular bonding. In line–angle formula, hydrogen atoms are not shown.

Explanation of Solution

Given compound:

cis-1,2-Diethylcyclobutane

Structural formula and line–angle formula:

From the name of the compound, it is clear that the main core of the compound is a four membered cyclic ring. Two ethyl groups are attached at first and second carbon atom in such a way that both the ethyl groups are in same direction of orientation with each other.

The structural formula and line–angle formula of the given compound is,

Concept Introduction:

Condensed structural formula:

Structural formula in which grouping of atoms are done and in which the central atoms along with the other atoms are connected to them are treated as group is known as Condensed structural formula.

Line–angle formula:

Structural formula where a line represent carbon‑carbon bond and the carbon atom is considered to be present in each point and the end of lines is known as Line-angle structural formula. This is a shorthand representation of an organic molecule with lines which represents its molecular bonding. In line–angle formula, hydrogen atoms are not shown.
