Question

what is emperical formula??give 1 example.​

Answer 1

Explanation:

Empirical formula → It is the simplest formula of a compound which gives a ratio of different atoms present in one molecule of the compound. E.g.- One molecule of ethylene (molecular formula C2H4) contains two atoms of carbon and four atoms of hydrogen. Its empirical formula is CH2.

Answer 2

Answer :

Empirical Formula :

The empirical formula is the simplest whole number ratio of atoms present in a compound.

Molecular Formula :

The molecular formula is the exact number of different types of atoms present in a molecule of a compound$.$

➝ Two or more compounds may have the same empirical formula but molecular formula cannot be same.

Example :

Molecular formula of Glucose :

$\bigstar\:\boxed{\bf{\purple{C_6H_{12}O_6}}}$

Simplest whole number ratio :

C : H : O = 6 : 12 : 6 = 1 : 2 : 1

Empirical Formula : CH₂O
