What is an example of a polarity of bonds practice problem?

Answer 1

A possible example would be: Is water and #CO_2# non-polar or polar?

To determine if something is polar or non-polar, you need to draw the Lewis Structures and use the resulting molecular geometry.

Since water has four bonding sites—two lone pairs of electrons and two hydrogen atoms—its bent tetrahedral geometry means that it has a dipole moment that is greater than zero for the reasons given in brackets.

#CO_2# on the other hand has a dipole moment of zero because it's geometry is linear, meaning the two oxygen molecules lie to the left and right of the oxygen, whose pulling forces cancel each other out.

In summary, a molecule is considered non-polar if its dipole moment is zero, and polar if its dipole moment is greater than zero.

I hope my response to your query was helpful.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
