Answer 1

Hi there,

The odd one out in the above options is Carbon.

Helium and hydrogen and air belong to the same category. All of them are gasses and are found in air. where as carbon combines itself with metals and then exists in gaseous states.

I hope you are satisfied with the answer above.

Thank you.

Answer 2

Odd one among the following: A)hydrogen,B)helium,C)carbon, D)air  ****************************************** Correct Answer is :option c: Carbon  Reason:  All other molecules like helium and hydrogen are part of air composition except carbon which is an atom  which cannot exist independently.   Air is a homogenous mixture of gases like Nitrogen-78% Oxygen-21% Argon-1% CO2-0.03% Other  gases ...LIKE  HELIUM and hydrogen. But carbon is a non metal which combines with oxygen and forms CO2
