    C-Mg, which is more electronegative: C or Mg?

    C so for c-mg its <-+ .... and for the mg-br bond its +-> evethough its in the same molec as c-mg where c is more electroneg?

    S-delta negative for carbon because it is more electronegative than magnesium

    Would that make it a polar molecule or a nonpolar?

    Polar. But what about the mg-br bond

    Keep in mind, when we are identifying polar or non polar molecules, we are looking at covalent bonds, Ionic compounds are not polar molecules. But, polar molecules consists of covalent bonding which is caused by sharing unequal amount of electrons. Metals on the other hand, does not share electrons because they ionically bond with nonmetals meaning they transfer valence electron between atoms whereas covalent bonds share electrons between non metals.

    so the dipole moment for mg-br is 0? because its an ionic bond?

    but its polar covalent bec the difference in dipole moment is less than 1.9

    The dipole moment for MgBr and all ionic bonds is significantly high.

    What is polar covalent? MgBr?

    But MgBr is not covalent :(

    It's an ionic compound with ionic bonding.
