Which physical property of di-hydrogen is wrong?

Options

ATasteless gas
BOdourless gas
CColourless gas
DNon-inflammable gas

Correct answer

D. Non-inflammable gas

Step-by-step solution

H 2 Is the lightest element ever and is a tasteless, odourless, colourless, and highly combustible gas. It's also in most organic compounds Hydrogen is a highly inflammable gas. This is because it burns in air to give water. The reaction is as follows: 2 H 2  + O 2  → 2 H 2  O .
