Question

An organic compound contains 12.7 6% carbon 2.1 3% hydrogen and 85.1 1% bromine it vapour density is 94 find the molecular formula of the compound

Answer 1

Answer:

bxbzvvsvsha

Explanation:

Answer 2

Answer:

the empirical formula of this compound is.....

H2CB

Therefore;

Molecular formula=n × empirical formula. n= molecular mass of compund/empirical formula mass

now,

molecular mass= 2×vapour density

therefore n= 2×94/94

=2

molecular formula= 2 ×H2CB

= H4C2B2
