Question

Which of the following is/are true about hydrogen:-

• A. Hydrogen gas is combustible and supporter of combustion
• B. Hydrogen gas is combustible and non-supporter of combustion
• C. Hydrogen gas is incombustible and non-supporter of combustion
• D. Hydrogen gas is incombustible and supporter of combustion

Answer 1

The correct option is B

Hydrogen gas is combustible and non-supporter of combustion

Hydrogen is combustible and non-supporter of combustion and this could be understood by a small activity in which if burning candle is placed in a hydrogen gas-filled gas jar with its mouth downwards then light candle gets extinguished but the gas burns with a pop-up sound. This shows that hydrogen is combustible but is a non-supporter of oxygen.
