Look up the electronegativities of each element and subtract. If the difference is about 1.8 or so that is approximately the 50-50 point between covalent and ionic with ionic being higher than 1.8. Compounds usually are labeled as covalent, polar covalent, and ionic.
Since polar covalent is not part of the question, anything <1.8 will e covalent and anything over 1.8 will be ionic. For example, Li is about 1 and Br is about 3. the difference is about 2 which means ionic. C is about 2.5 and Cl is about 3.0 for a difference of 0.5 which makes it covalent. You take it from here.
