Asseration: `SCl_(4)`, does not havea tetrahedral structure. Reason: `Se` in `SeCl_(4)` has two lone pairs.A. If both assertion and reason are true and reason is the true explanation of the asseraton.B. If both assertion and reason are true and reason is not the correct explanation of the assertion.C. If assertion is true bit reason is false.D. If assertion is false but reason is true. |
Answer» Correct Answer - C `SeCl_(4)` possess see saw geometry, which can be regarded as a distored trigonal bipyramidal structure laving one lone pair `(lp)` of electrons in the basal position of the trigonal bipyramidal. See-saw geometry of `SeCl_(4)` molecules arises due to the `sp^(3)d` hydridisation of the central atom. the distortion in shape is due to the presence of one lone pair of electrons. |
