Question

For each of the following compounds,

Draw the Lewis structure of a compound with clarity and accuracy

Determine if a chemical bond is either non-polar, polar, or ionic with clarity and accuracy

Determine if a compound is either non-polar, polar, or ionic with clarity and accuracy

a)𝐶𝐹4

b)𝐻𝐵𝑟

c)𝑁2

Answer 1

Cannot draw Lewis structures on this Wyzant platform, but will do my best to describe the structures.

a) CF4 - has 4 + 28 = 32 valence electrons with C as central atom

Put C in the center and attach 4 F atoms each with a single bond. Put 3 lone pairs of electrons around each F atom. Done. The C-F bond is polar. The compound is not polar

b) HBr - has 1 + 7 = 8 valence electrons. H-Br. Put 3 lone pairs of electrons around the Br atom.

The H-Br bond is polar. The compound is polar.

c) N₂ - has 5 + 5 = 10 valence electrons

:N ≡ N: and put 1 lone pair of electrons on each N atom (as shown). The bond is not polar and the compound is not polar.
