Reason R: Atomic number of hydrogen is 1 and it is a very light element.
In the light of the above statements, choose the correct answer from the options given below
- (A) is true but is false
- (B)Both and are true but is NOT the correct explanation of ✓ Correct
- (C) is false but is true
- (D)Both and are true and is the correct explanation of
Answer: (B)
Solution
Hydrogen is an environment-friendly fuel because its combustion yields only water, , releasing no carbon oxides or other pollutants, so the assertion is true. It is also true that hydrogen has atomic number one and is the lightest element. Its clean character, however, arises from the nature of its combustion product and not from its atomic number or low mass, so the reason, although a true statement, does not account for the assertion. Both statements are true but the reason is not the correct explanation of the assertion.
