Compounds Mixtures
They are pure in nature They are impure in nature
Formed in specific proportion by chemical combination No specific proportion for mixture and are formed by physical combination
Differ from characteristics of individual components Similar to the characteristics of its individual components
Separation of constituents by chemical methods Separation by physical methods
Melting points and boiling points are fixed Melting points and boiling points are not fixed
Results in the formation of new substance No any new substance will be formed
Conclusion

The definition for the term compound and its difference from mixture was explained.
