Frequently Asked Questions

Yes. It is flammable, toxic if inhaled, and can affect the central nervous system. It requires careful handling in industrial settings.

Its main use is as an intermediate in the production of silicone polymers. It was also historically used as a refrigerant and solvent.

Chloromethane (CH₃Cl) has one chlorine atom. Chloroform (CHCl₃) has three chlorine atoms and is a liquid at room temperature, historically used as an anaesthetic.

It is both. It is produced industrially, but also naturally by marine algae, volcanoes, and forest fires.

Memory Aids

Mnemonic

Think: 'Chloro' (like in chlorine, a greenish gas) + 'methane' (the simplest hydrocarbon). It's methane with a chlorine swap.
