Some Chemical Compound and their Formulae

Some Chemical Compound and their Formulae for RRB NTPC and SSC Exams

Chemical compound notes for RRB NTPC and SSC Exams

In This lecture series you can learn about Some of important chemical compounds and their formulae. It will be very usefull for upcoming RRB NTPC, RRC and SSC Exams.


A Compound is a pure substance composed of two or more elements. Chemically combined with one another in a fixed proportion. It has totally different properties from its constituent particles, e.g - Water (H₂O), Methane (CH₄), etc.
