For each compound, state whether it’s binding is covalent, ionic, or a mixture of covalent and ionic.

a) NaCl

b) NaOH

c) CH3Li

d) CH2Cl2

e) NaOCH3

f) HCO2Na

g) CF2



How can you tell if it’s ionic or covalent bonds or a mixture?

I know a) = covalent because its easier for Cl to gain an electron to become Ar. But how can you tell for the rest? And how do you know which is the central atom when drawing Lewis structure?



please explain so I can follow along, thank you :)

Covalent bonds are between substances of the same nature. Most commonly, you'll find covalent bonds between gases and ionic bonds between a metal and a gas such as Na (alkali metal) and Cl- (gas). A molecule considered a mixture contains both a covalent bond and ionic bond such as NaOCH3. The covalent bonds exist between carbon and the hydrogens while the ionic bond is between Na ( a cationic metal) and the methoxy (OCH3) which carries a negative charge. If you need more detailed help with Lewis Structures request a session I would love to help!

I explained it in the comment section but I’m not sure where it went. We can schedule a session and I guarantee that you will understand the concept and be able to apply it in the future problems.
