Examples

By Part of Speech

adjective

British English

  • The bromoacetone precursor is stored separately.
  • A bromoacetone derivative was isolated.

American English

  • The bromoacetone reagent is highly volatile.
  • A bromoacetone solution was prepared.

Examples

By CEFR Level

B2
  • Bromoacetone is a dangerous chemical and should only be handled in a lab.
  • Historically, bromoacetone was used in World War I.
C1
  • The researcher synthesized bromoacetone via the halogenation of acetone in the presence of an acid catalyst.
  • Due to its potent lachrymatory properties, the use of bromoacetone in warfare was later prohibited by international treaty.

Learning

Memory Aids

Mnemonic

Think: 'BROther MOnkey ACETs (little acids) ONE' -> BRO-MO-ACET-ONE. It's a compound where a bromine atom (Br) is attached to acetone.

Conceptual Metaphor

Not applicable for this purely technical term.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate as 'бром ацетон' as separate words. The standard Russian chemical term is 'бромацетон'.

Common Mistakes

  • Incorrect hyphenation/spelling: 'bromo-acetone', 'bromo acetone'.
  • Mispronouncing the '-acetone' part as /ˈæsɪtɒn/ instead of /ˈæsɪtəʊn/ (UK) or /ˈæsɪtoʊn/ (US).

FAQ

Frequently Asked Questions

Yes. Bromoacetone is a toxic, lachrymatory (tear-inducing), and irritating compound. It must be handled with extreme care under controlled laboratory conditions.

No. Bromoacetone is a specialized industrial and laboratory chemical reagent. It is not a component of any consumer products.

In organic synthesis, bromoacetone is used as an alkylating agent, introducing the CH3COCH2- group into other molecules to build more complex structures.

No. Its use in warfare is banned under the Chemical Weapons Convention. It is now of historical interest only in that context.
