How can the shaoe of a molecule determine it's polarity

The shape of the molecule will determine the direction of each of the individual bond dipoles, and thus, will always play a role in determining the polarity of the molecule as a whole

Explanation:

I hope I hlep :)

1. The approximate shape of a molecule can be predicted from the number of electron groups and the number of surrounding atoms.

2. The molecular polarity can be established by determining the vector sum of all bond dipoles.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
