In the following question a statement of Assertion →A) followed by a statement of Reason →R) is given. Choose the correct option out of the choices given below each question.
Assertion →A) : The empirical mass of ethene is half of its molecular mass.

Reason →R) : The empirical formula represents the simplest whole number ratio of various atoms present in a compound.

i) Both A and R are true and R is the correct explanation of A.

ii) A is true but R is false.

iii) A is false but R is true.

iv) Both A and R are false.

→i) Both A and R are true and R is the correct explanation of A.
The molecular formula of ethene is C₂H₄ and the empirical formula is CH₂. The molecular mass of ethene is 28 and the empirical mass is 14. The empirical mass is half of its molecular mass. The empirical formula shows that the ratio of C:H is 1:2.
