Every Compound can be represented by a formula. There are 3 types of formula:
Empirical Formula –> Simplest whole number ratio of atoms present
Molecular Formula –> Total number of atoms in one molecule
Structural Formula –> Shows how the atoms are linked together in a molecule
Note:
=> Structural Formula DOES NOT give the molecular shape

Many know me as the Ten Year Series book author for JC A-Level H2 Chemistry and O-Level Pure Chemistry. My 19+ years of coaching experience (since 1999) with more than 1500 students from 180+ JCs and Secondary Schools has allowed me to understand the true reasons why students are not able to perform well in Chemistry. Most importantly, my strength lies in using everyday analogies (even grandmothers can understand!) to simplify abstract concepts. Also, my teaching methodology has been designed to be fun, enjoyable and effective for my students. If you want to have an enjoyable time learning Chemistry and being motivated to excel in Chemistry, contact me today at 98287357
