C. TNT
D. NTT
C. TNT
TNT is the standard abbreviation for 2,4,6-trinitrotoluene, a chemical compound with the molecular formula C₇H₅N₃O₆. It is widely known for its use as an explosive.
The name helps explain its structure:
- Tri: Indicates three.
- Nitro: Refers to the three nitro groups (–NO₂).
- Toluene: Refers to the parent compound, which has a methyl group (–CH₃) attached to a benzene ring.
The numbers 2,4,6 identify the positions of the three nitro groups on the ring, taking the carbon bearing the methyl group as position.
Why are the other options incorrect?
TNA, TAN and NTT are not the standard abbreviation for 2,4,6-trinitrotoluene. The correct abbreviation is TNT.
