Question

What are the differences between conformation and configuration?

Answer 1

Differences between conformation and configuration:

Confirmation	Configuration
Conformations have low energy barrier, which varies from 4.2 to 46 kJ per mole.	The difference in energy between the two configurations is more than 84 kJ/ mole.
Conformers are non-ionisable.	Configurations are ionisable.
Conformers are easily interconvertible.	Configurations are not easily interconvertible.
A molecule could have an infinite number of conformations.	A molecule can have only one configuration.
