Is BF3 a polar or non-polar molecule? Why?
non-polar because even though B-F bond is polar, the symmetrical geometry makes the overall molecule non-polar.

500
Which of the following are common reducing agents? (pick as many as are correct)
B2H6, I2, H2SO4, CrO3, NAD+, NADH
Reducing agents get OXIDIZED, and oxidation is losing electrons. Therefore, reducing agents often contain metal ions or hydrides (H-).
Answers: B2H6, NADH
