Question

Draw skeletal structures for each pair of isomers in Problem 7.

Short answer

The skeletal structuresfor each pair of isomers in Problem 7are shown below.

Step-by-step solution

Step 1: The skeletal structure

In this series of atoms bonded together, it is a form of the essential structure of the compound. This skeleton can consist of chairs, branches, and rings of bonded atoms. Example: The skeletal structure of a sec-butyl tert-butyl ether is shown below.

Here, the carbon atom is shown as corners. Bonding is shown by a line. Single bond single line, double bond double line, triple bond triple line.

Definition of the cis and trans isomer

Isomers are compounds with the same molecular formula but with a different arrangement of atoms.

Cis-isomer is represented with both the substituents pointing in one direction.

Trans-isomer is represented with both the substituents pointing in opposite directions.
