Question

Which of the following statements is NOT correct regarding dihydrogen?

• A. It is colorless and tasteless gas.
• B. It burns with a pale blue flame.
• C. It is a polar water-soluble gas.
• D. It is lighter than air.

Hint:

Dihydrogen is a nonpolar molecule and is almost insoluble in water.

Answer 1

The Correct Option is C

Step 1: Structure
The $H-H$ bond joins two identical atoms, so there is no dipole. This makes the molecule nonpolar and sparingly soluble in water.

Step 2: Result
Statement (C) is the false one.

Final Answer:
Statement C is wrong. \[ \boxed{\text{(C)}\ \text{It is a polar water-soluble gas}} \]
