How do you count unsaturation from C8H10ClNO and draw three isomers?

[useful_idiot]

How many elements of unsaturation are implied by the molecular formula C8H10ClNO? Draw Three structure, one containing ether and amine group, one containing amide group, one containing amine and ketone group.

I have no clue where to begin and read the chapter. as long as it is understandable. I will be very thankful...

Sorry, we can't do that. It's against forum rules. Please see the second line of my signature.
