Chemical properties of sodium MCQ - Practice Questions with Answers

Solve 1 Chemical properties of sodium questions for RAS/RPSC preparation.

Practice questions

Q1Given below are two statements: Statement I: Sodium metal is stored in kerosene oil because it is highly reactive. Statement II: Sodium metal reacts vigorously with nitrogen. In the light of the above statements, choose the most appropriate answer from the options given below.

A Both Statement I and Statement II are correct.

B Both Statement I and Statement II are incorrect.

C Statement I is correct but Statement II is incorrect.

D Statement I is incorrect but Statement II is correct.

Explanation

Sodium is an alkali metal and reacts very quickly with oxygen and moisture in air, so it is kept under kerosene oil to cut off contact with air and water. That makes the first statement correct. Sodium does not react vigorously with nitrogen under ordinary conditions; lithium is the alkali metal best known for forming nitride directly. Therefore the claim about a vigorous reaction with nitrogen is incorrect. The choices saying both statements are correct, both are incorrect, or only the nitrogen statement is correct do not match the chemical behaviour.
