Question

A molecule of an organic compound contains eight atoms of hydrogen. Its empirical formula contains two atoms of carbon , four atoms of hydrogen and one atom of oxygen[C2H4O]. What is its molecular weight ? (Write only the value of the answer - DO NOT write units ) . *​

Answer 1

☆Emperical formula:

》It is the simplest written form of any organic compund.

》Every compound has its emperical formula.

》There cannot be anything less simpler than emperical formula.

☆Molecular formula:

》It is the complex form,having its basic as emperical formula

》atoms present in the compound will be present in the multiple of emperical formula = and resulting will give us the molecular formula for compound.

☆Solution:

• In the ques the hydrogen are 8 and in the emperical formula $\ C_2 H_4 O$ has 4 hydrogens.

•So means, molecular formular is in the multiple of 2.

•• multiply every atom with 2.

☆Molecular formula will be:

$\bf C_4 H_8 O_2$
