Preparation of Pentane: this chemical can be prepared by pent-1-ene. This reaction will need reagent platinum black. The reaction is a kind of Hydrogenation reaction.

Pentane can be prepared by pent-1-ene

Uses of Pentane: This chemical is one of the primary blowing agents used in the production of polystyrene foam. Because of its low boiling point, low cost, and relative safety, pentane is used as a working medium in geothermal power stations. It is added into some refrigerant blends as well. Pentanes are relatively inexpensive and are the most volatile alkanes that are liquid at room temperature, so they are often used in the laboratory as solvents that can be conveniently evaporated. They are also often used in liquid chromatography.

When you are using this chemical, please be cautious about it as the following:
Pentane is extremely flammable and harmful. It is toxic to aquatic organisms whic may cause long-term adverse effects in the aquatic environment. It may cause lung damage if swallowed. You should keep it away from sources of ignition - No smoking. When using it, you can take precautionary measures against static discharges. If swallowed, you should not induce vomiting: seek medical advice immediately and show this container or label.

You can still convert the following datas into molecular structure:
(1)Canonical SMILES: CCCCC
