An organic compound on analyis found to ...

An organic compound on analyis found to contain 92.3 % carbon and 7.7% hydrogen. It vapour density is 39. Find its molecular formula.

Text Solution

Verified by Experts


`therefore` Empirical formula = CH
Molecular mass = `2 xx 39 = 78`
`therefore` Molecular formula `=(CH)_(n) =(CH)_(6) = C_(6)H_(6)`
