How many isomers are possible for hexane?
five hexane
All five hexane constitutional isomers have the same molecular formula, C6H14, and the same molecular weight, 86. However, each one of the hexanes has a unique boiling point….Constitutional (structural) Isomers:
| # of Carbons | Acyclic Alkane | # of Isomers |
|---|---|---|
| 4 | butane | 2 |
| 5 | pentane | 3 |
| 6 | hexane | 5 |
| 7 | heptane | 9 |
What are the isomers of ethene?
Geometric (cis-trans) isomerism These are called cis-but-2-ene (where the groups are on the same side) or trans-but-2-ene (where they are on opposite sides). Cis-but-2-ene is also known as (Z)-but-2-ene; trans-but-2-ene is also known as (E)-but-2-ene.
What condensed structural formula?
Condensed structural formulas show the order of atoms like a structural formula but are written in a single line to save space and make it more convenient and faster to write out. Condensed structural formulas are also helpful when showing that a group of atoms is connected to a single atom in a compound.
