4a. classify compounds as covalent, polar covalent or ionic. if polar covalent show the Direction of the electrons using an arrow
a. OF
b. NaCl
c. H2O
D. NF3
i have one question tomorrow i have finals and i don't know how to classify if something is ionic, covalent, or acid please help me! thanks in advance

One quick way to tell is how far apart they are on the periodic table. If right next to each other, the bond is covalent. If a couple elements are between them, they are probably polar. If far apart, like metale and nonmetals, they are ionic
That would make H2O polar, and probably NF2 The electrond will still flow toward the atom closest to the upper right of the periodic table, so Fluorine and oxygen will have arrows popinting to them.
The real way to exactly tell is by subtracting the value of electronegitivity If the difference is > 1.6, the substance is ionic. If the difference is < .5, it is covalent. If between and including those values, it is polar

They are classified based on the electronegativity of the constituent atoms. If the electronegativity of each atom in the molecule is approximately the same, its a nonpolar bond. If the electronegativity difference is very large, you have an ionic bond and if its in between its a polar covalent bond. Electrons tend towards the more electronegative atom.
Theres a cutoff between ionic and polar but usually your teacher would probably tell you. As far as i know there isn't a tabulated value that separates the 2 cases.

a. wrong formula, maybe OF2 ?
b. Ionic substance Consist of Na+ions and C l- ions.
c.Covalent planar, angular polar having 2 bond pairs and to two bondpairs, planar angular, and polar
d. trigonal pyramimd , polar , and covalent. with three bond pairs and one lone pair
