Question

What is a pure compound?

Answer 1

Hint:A compound is formed due to its different types of bonds formed between the constituents of it. It differs due to the nature of bonds between the atoms of elements which actually form it. A compound is a pure substance.

Complete step-by-step answer:- A pure substance is a substance which has only one type of atom or molecule thereby having a constant composition and structure.
- A compound is a pure substance which is formed from the molecules of constituent elements. They are formed when elements are joined and held together by strong forces called chemical bonds.
- Elements and compounds are pure substances. Elements are substances composed of only one type of atom. For example, copper, silver, oxygen etc.
- On the other hand, compounds are substances formed by the combination of two or more elements in a definite ratio. Water is a compound as it is formed by the combination of hydrogen and oxygen in a fixed ratio. It has a constant ratio throughout

Note:A substance can be either an element, or compound or a mixture. Elements and compounds have a constant composition throughout and can thus be said as pure substances. While a mixture has different characteristics than a pure substance. They are known as impure substances. Mixtures are composed of different compounds mixed together, or more than one pure substance combined together in any proportion.
