Practice: Which of the following correctly identifies the chemical bond between a carbon and oxygen atom?
a) Polar Covalent
b) Pure Covalent
c) Nonpolar
d) Ionic
Dipole arrows are used anytime a molecule possesses a dipole moment, which happens when a molecule is polar.
Concept #1: Periodic Trend
Electronegativity increases moving from left to right and going up a group.
Concept #2: Dipole Moment
Dipole arrow is representative of bond polarity between 2 elements and points towards a more EN element.
Example #1: Calculate the difference in electronegativity values between carbon and fluorine.
Concept #3: Further Chemical Bond Classifications
Differences in EN between bonds help us classify the different types of bonds possible.
Example #2: For those listed below, which has the most polar bond?
Practice: Which of the following correctly identifies the chemical bond between a carbon and oxygen atom?
a) Polar Covalent
b) Pure Covalent
c) Nonpolar
d) Ionic
