CHXI01:SOME BASIC CONCEPTS OF CHEMISTRY

306605 Assertion :
Molecular weight of a compound is 44 if its vapour density is 22 .
Reason :
Vapour density \(\times 2=\) Molecular weight.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
