Interpretation:
Thegiven molecular models are to be converted into a condensed structural formula, a Kekule structure, and a skeletal (line) structure.
Concept Introduction:
Molecular model of a chemical compound represents the three-dimensional position of the atoms along with the bonds between them. The atoms are represented by spheres, connected by rods, which represent the bonds.
Wedges represent the bonds toward the viewer, dashes represent the bonds away from the viewer, and solid lines represent the bonds in the plane of the image.
The structural formula of a chemical compound consists of the graphic representation of the molecular structure and the arrangement of atoms.
In an organic molecule, the structure representation of atoms takes place by single or double bonds without lone pairs; it is called theKekule structure.
In an organic molecule, bonds are not represented by single lines or branched chains; it is called the condensed structural formula.
In an organic molecule, when the structure consists of straight lines that represent

Explanation of Solution
a)
In the condensed structural formula, the compound consists of two
In thestructure given below, there are three carbon atoms, in which two carbon atoms are linked to the
The skeletal structure consists of a line representation of the bond between atoms. In this structure, carbon and hydrogen atoms are not shown except heteroatoms. Two oxygen atoms are linked by a single line and one oxygen atom is linked by double lines. A single line representsa single bond and double lines represent double bonds.
b)
The condensed structural formula consists of two functional groups that are
.
In the structure given below, there are four carbon atoms in the compounds that are linked by alternate single and double bonds, in which one carbon atom is linked to the
The skeletal structure consists of the line representation of the bond between atoms. In this structure, carbon and hydrogen atoms are not shown except heteroatoms. A single line represents single bonds and double lines represent double bonds. The
Given information: The molecular model of the compound is represented below:
c)
In thecompound given below, there are two
In the structure given below, there are sixcarbon atoms including the
The skeletal structure contains the line representation to show the bond between atoms. In this structure, carbon and hydrogen atoms are not shown except heteroatoms. Oxygen atoms are linked to the carbon atom with single and double lines, and the
