“Chemical compound with formula” is written about the common name and formula of chemical compounds. If you analyse previous years’ question papers of Railway Group – D, Railway NTPC, SSC or Other State Government Exams you will find that in General Study (GS) Section questions Related to Chemical Compound asked many time like :—–

1) What is the Chemical formula of Bleaching Powder ? 

2)Which Chemical Compound is known as Dry Ice ? 

3) What is the Chemical formula of Blue Vitriol ? etc.

To master these type of questions in General Study Section we provide detailed notes and pdf, so don’t forget to read it.

What is mean by Chemical Compound?

Chemical substances consist of many identical molecules composed of atoms from more than one element by chemical bonding in fixed proportion are called Compounds.

Examples of Chemical compounds :- H₂O, CO₂, Nacl, CaOH, etc.

What is the Chemical formula of Compound?

It is the sybolic representation of a compound  made up of atoms of  two or more elements in fixed mass ratio. eg – H₂O made up of two hydrogen atom and one oxygen atom.

Types of Chemical Compounds

Generally their are three types of chemical compounds — 

1) Ionic Compound

The compound formed by the transfer of electron from a metal to a non-metal atom is known as Ionic or Electrovalent compound. example – NaCl, MgCl₂, CaO, etc.

2) Covalent Compound 

The compounds that are the result of sharing of electron are called Covalent Compound. example – H₂, CO₂, N₂, etc.

3) Coordinate Compound

It has special type of covalent bond. These compounds exist in all the three states (solid, liquid and gas) under ordinary condition.
