Match each molecular formula to the corresponding empirical formula.
lawyer [7]

Explanation:

C₄H₈O₂                      C₂H₄O

C₄H₁₂O₄                       CH₃O

C₂H₁₀O₂                      CH₅O

The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio of the atoms of the different elements that makes up a compound.

The molecular formula is the true formula of the compound. It expresses the actual number of moles of atoms of the different elements present in a molecule of the compound.

C₄H₈O₂                      C₂H₄O

4: 8 : 2 divided by 2 gives 2: 4 : 1

C₄H₁₂O₄                       CH₃O

4: 12: 4  divided by 3 gives 1: 3: 1

C₂H₁₀O₂                      CH₅O

2: 10: 2 divided by 2 gives 1: 5: 1

Explanation : The scientist John Dalton proposed the atomic theory which had the postulates as follows.


i) All matter/substances consists of indivisible particles known as atoms.

ii) Atoms of the same element/substance are similar in mass,shape and size, but differ from the atoms of other elements.

iii) Atoms obey the law of conservation of energy which says atoms cannot be created or destroyed.

iv) Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form any compound atoms.

v) Atoms of same element can combine in ratio with more than one to form two or more compounds.

vi) The atom is considered to be the smallest unit of matter that can take part in a chemical reaction
