Which is a flammable substance?
Think it through first, then pick an option.
- a Benzene
- b Ether
- c Radium
- d Xylene
Answer and explanation
Correct answer: b Ether
Alcohol and ether are flammable; keep them away from fire and heat.
Why the other options are wrong
- a Benzene: In the book's table benzene is toxic and a health hazard, not flammable. In real life benzene burns too, but in the exam you go by the book's list, so the answer is ether.
- c Radium: Radium is a radioactive substance, not a flammable one.
- d Xylene: In the book's table xylene is a health hazard substance. In real life xylene burns too, but in the exam you go by the book's list, so the answer is ether.
