Answer
Answer 1
S, 1s2, 1s2, 2, 2p6, 3s2, and 3p4 Br = [10]ns2–5 sp3–d hybridization. sp63-cl hybridization. lp = 1. cf_4 = 1s2, 1s2, 1sp2, NCl_3 N_7 = lp trigonal pyramidal. dlg hybridization molecular geometry is trigonal bipyr
Answer 2
A Lewis structure can be used to determine both the electronic and molecular geometry of a molecular molecule. It is a skeletal structure that includes all elements and non-bonding particles. Two electrons signify one electron pair. The following table shows the results of hybridization using different combinations and lone electron pairs. The electronic configuration of the valance shell is 3s, 3p. It contains 6 valance electrons that are involved in bonding. Each S electron forms a single bond with four Br electrons, and there is one remaining pair. It has four bond pairs and one lone pair. Accordingly, the hybridization of this compound according to the above table is sp.d. The electron geometry is trigonoal bipyramidal. Therefore, A is the correct choice.
Answer 2 compound CF4, Cis central atom. The It contains 4 valance electrons that are involved in bonding. Each C electron forms a single bond with four F-atoms. It has four bond pairs and one lone pair. According to the table above, the hybridization of this compound is sp. The electron geometry is tetrahedral. As shown in the figure, the molecular geometry also tetrahedral. C is the correct choice.
Conclusion
Above is the solution for “Number 1-6 1. What is the molecular geometry of SBr4? A) seesaw B) square planar C)…“. We hope that you find a good answer and gain the knowledge about this topic of science.
