Definition

Meaning and Definition

A halogenated hydrocarbon used primarily as a refrigerant and propellant, with the chemical formula CClF₃.

A specific type of chlorofluorocarbon (CFC) gas, historically used in refrigeration and air conditioning systems, but now largely phased out due to its ozone-depleting properties.

Dialectal Variation

British vs American Usage

Differences

No significant linguistic differences in usage; differences are primarily in regulatory context and historical phase-out schedules.

Connotations

Strongly associated with environmental damage, ozone layer depletion, and the Montreal Protocol.

Frequency

Extremely low in general discourse; frequency is confined to historical, technical, and environmental policy contexts.

Watch out

Common Mistakes When Using “chlorotrifluoromethane”

  • Misspelling as 'chlorotrifluromethane' (missing an 'o').
  • Incorrect hyphenation: 'chloro-trifluoro-methane' is less standard.
  • Confusing it with 'trichlorofluoromethane' (CFC-11), which has three chlorines.

FAQ

Frequently Asked Questions

Its production and consumption for most uses are banned globally under the Montreal Protocol. Very limited, critical-use exemptions may exist for specialized laboratory or medical applications.

It was largely replaced by hydrofluorocarbons (HFCs) like R-134a, which do not deplete the ozone layer, though many HFCs are now also being phased down due to their high global warming potential.

Like many refrigerants, it is an asphyxiant and can displace oxygen in confined spaces. Its primary environmental hazard, however, is its effect on the stratospheric ozone layer.

It is pronounced phonetically: KLOR-oh-TRY-floor-oh-METH-ane. The stress typically falls on the 'tri' and 'meth' syllables.

A halogenated hydrocarbon used primarily as a refrigerant and propellant, with the chemical formula CClF₃.

Chlorotrifluoromethane is usually technical/scientific in register.

Learning

Memory Aids

Mnemonic

Break it down: CHLORO (like chlorine) + TRI (three) + FLUORO (like fluorine) + METHANE (a simple gas). Think: 'A methane gas with one chlorine and three fluorines attached.'

Conceptual Metaphor

Often framed as a 'villain' in the story of atmospheric protection or a 'relic' of pre-environmental awareness industrial chemistry.
