IC4 gas, also known as isobutane, is a type of hydrocarbon gas with the chemical formula C4H10. It's an isomer of butane, meaning it has the same chemical formula but a different molecular structure. Here's a breakdown:
Understanding Butane and Isobutane
| Feature | Normal Butane (NC4) | Isobutane (IC4) |
|---|---|---|
| Chemical Formula | C4H10 | C4H10 |
| Carbon Structure | Four carbon atoms in a chain | One carbon atom linked to three others |
| Other Name | n-Butane | Methylpropane |
Key Differences Explained
- Normal Butane (NC4): The carbon atoms form a straight chain, like beads on a string.
- Isobutane (IC4): One carbon atom is connected to three other carbon atoms, creating a branched structure. The reference states, "If one of those carbon atoms links the other three carbon atoms... it is isobutane (called IC4)."
Common Uses
- Refrigerant: Isobutane is often used in refrigeration systems.
- Propellant: It is commonly used as a propellant in aerosol sprays.
- Fuel: Isobutane can be used as a fuel for heating, cooking, or in certain types of portable gas stoves.
Summary
In essence, IC4 gas specifically refers to isobutane, a structural isomer of butane characterized by its branched carbon chain structure. Its chemical formula remains C4H10.
