for a molecule to be polar it must have
Chemical polarity Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other.
The Polar Express (film) On the night of Christmas Eve, a Grand Rapids, Michigan boy is growing bitterly skeptical of the existence of Santa Claus. As he struggles to sleep, he is roused by the arrival of a steam locomotive on the street outside his home, and dons his robe to investigate, tearing the robe's pocket as he retrieves it. Outside, the train's conductor (Tom Hanks) introduces the train as the Polar Express, bound for the North Pole. The boy initially declines to board, but jumps aboard the train as it pulls away.
