Which of following is not a property of red phosphorus?
1 Insoluble in carbon disulphide
2 It does not show chemiluminescence by action of air
3 It forms phosphine when treated with hot sodium hydroxide solution
4 It is non-poisonous
Explanation:
Red phosphorus possess iron grey lustre. It is odourless, non-poisonous and insoluble in water as in carbon disulphide. It does not show chemiluminescence by action of air. Thus, the option (3) is correct.
