For example, there are two alkanes with the formula C 4 H 10: Figure 4. Click on the link to see a 3D rotatable model of n-butane and 2-methylpropane.Generally the number of isomers increases. You can demonstrate this to yourself by drawing all possible structures for propane (1), butanes (2), pentanes (3), and hexanes (5). One way to think about this is as follows: Each carbon you add can attach to any of the carbons already present in any isomer of the molecule. Feb 28, 2022 · Functional isomers are constitutional isomers bearing different functional groups. eg. 1: Acetone (1) and propanal (2) are constitutional isomers. They contain different functional groups. Thus, 1 and 2 are functional isomers. see also skeletal isomers, positional isomers; Gamini Gunawardena from the OChemPal site (Utah Valley University) Generally the number of isomers increases. You can demonstrate this to yourself by drawing all possible structures for propane (1), butanes (2), pentanes (3), and hexanes (5). One way to think about this is as follows: Each carbon you add can attach to any of the carbons already present in any isomer of the molecule. When the group of atoms that make up the molecules of different isomers are bonded together in fundamentally different ways, we refer to such compounds as constitutional isomers.

The cis isomer has the two single hydrogen atoms on the same side of the molecule, while the trans isomer has them on opposite sides of the molecule. In both molecules, the bonding order of the atoms is the same. In order for geometric isomers to exist, there must be a rigid structure in the molecule to prevent free rotation around a bond.
