Question

Identify the set which is not correctly matched in the following:

• A. PH\(_3\), colorless gas, rotten fish smell
• B. Cl\(_2\), greenish yellow gas, pungent smell
• C. Ne, fluorescent green gas, rotten egg smell
• D. SO\(_2\), colorless gas, pungent smell

Hint:

Noble gases like neon are colorless and odorless, unlike other reactive gases.

Answer 1

The Correct Option is C

Neon (Ne) is an inert, colorless, and odorless gas. The description of "fluorescent green gas, rotten egg smell" is incorrect. PH\(_3\) has a rotten fish smell, Cl\(_2\) is greenish yellow and pungent, and SO\(_2\) is colorless with a pungent smell, all of which are correctly matched.
