How to identify a compound as chiral or achiral
Look for carbons with four different groups attached to identify potential chiral centers.

Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral.

Here you're particularly interested in the C in the CH. However, take a look at the C in CH3. Why isn't it a chiral carbon?
