Chem Help Transcribed Image Text: TRUE or FALSE? Q: What determines the degree of polarity in a bond? Distinguish between nonpolar

Excerpt
1.0, the bond is moderately polar covalent. If the difference in electronegativities between the two atoms is 1.0 to 2.0, the bond is ghly polar covalent. If the difference in electronegativities between the two atoms is more than 2.0, the bond is ionic. True False

Chem Help Transcribed Image Text: TRUE or FALSE?
Q: What determines the degree of polarity in a bond? Distinguish between nonpolar
covalent, polar covalent, and ionic bonds in terms of relative polarity.
A: The relative electronegativity of the two bonded atoms determines the polarity of
a bond. If the difference in electronegativities between the two atoms is less than
0.4, the bond is nonpolar covalent. If the difference in electronegativities between
the two atoms is 0.4 to 1.0, the bond is moderately polar covalent. If the difference
in electronegativities between the two atoms is 1.0 to 2.0, the bond is ghly polar
covalent. If the difference in electronegativities between the two atoms is more than
2.0, the bond is ionic.
True
False
