Chf3 Hybridization

You have 3 highly electronegative atoms (fluorine) that pull electron density away from the hydrogen, so you have a somewhat polar molecule. Polarity in a molecule occurs due to the unequal sharing of valence electrons;. Water is a polar molecule because of the way the atoms bind in the molecule with more positive (+) charges on one side of the molecule and more negative (−) charges on the other side of the molecule. Linear - $\ce{sp}$ - the hybridization of one $\ce{s}$ and one $\ce{p}$ orbital produce two hybrid orbitals oriented $180^\circ$ apart. Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. This is especially true when the anion is stabilized as a result of aromaticity. hybridization of MD and HD trucks.
