FAQ

Frequently Asked Questions

Yes, it is toxic, harmful if inhaled, and a potential skin irritant. It must be handled in a fume hood with appropriate PPE.

Its systematic name is diiodomethane. It is not commonly known by a trivial name outside chemistry/geology.

No, it is a specialised chemical reagent typically purchased from scientific suppliers for laboratory use only.

Methylene iodide (CH2I2) has two iodine atoms on one carbon. Methyl iodide (CH3I) has one iodine atom and is a simpler, more volatile compound.

A dense, colorless liquid chemical compound (CH2I2), often used in mineralogy and chemistry for density separation.

Methylene iodide is usually technical / scientific in register.

Learning

Memory Aids

Mnemonic

Think of 'methylene' as a simple carbon unit, and 'iodide' with its heavy iodine atoms, making it a heavy liquid for sinking minerals.

Conceptual Metaphor

A liquid weight scale (used to measure density by sinking or floating).
