ionic bond, polar covalent bond, nonpolar covalent bond.
-
Br-Br is a nonpolar covalent because there is no difference between the two atoms' electronegativities.
C-H is polar covalent because the difference between the 2 atoms' electronegativities is above zero, but less than 2 (the difference is about 0.35)
Hope this helps.
