Question

Which of the following chemical starts the combustion process in the matchstick?

• A. antimony sulphide
• B. potassium chlorate
• C. phosphorous
• D. starch and wool

Answer 1

The correct option is C phosphorous

Phosphorous which is applied on the head of a matchstick has a very low ignition temperature of ${35}^{\circ }$ C. During rubbing, the heat produced due to friction is sufficient to attain this temperature and combustion takes place.

Option $C$ is correct.
