Hypothesize why these results are observed.arrow_forwardIn 1874, Dutch chemist Jacobus van't Hoff (1852–1911) and French chemist Joseph Le Bel (1847–1930) independently deduced that a carbon atom bonded to four atoms assumes a tetrahedral geometry. Prior to that time, it was believed that tetravalent carbons assumed a square planar geometry. One piece of evidence that can be used to support a tetrahedral geometry is the fact that molecules with the general formula CX2Y2 (where X and Y are either a hydrogen or a halogen atom) are always polar. Explain how this supports a tetrahedral geometry and rules out a square planar geometry.
