enantiomer

I'm a little stuck... Click here to teach me more about this clue!

'one of a pair the mirror image of the other' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'awkwardly mention ear' is the wordplay.
'awkwardly' indicates anagramming the letters.
'mention'+'ear'='mentionear'
'mentionear' anagrammed gives 'ENANTIOMER'.

'it's' is the link.

Can you help me to learn more?

(Another definition for enantiomer that I've seen is " Shape or its mirror image".)
