Web2. Lewis Structure of PCI5 Answer: Phosphorus having atomic no. 15 contains 5 electron in its outermost orbit i.e., 2, 8,5….chlorine having atomic no. 17 contains 7 electrons in its outermost orbit i.e., 2, 8, 7…each chlorine will gain 1 elerctron from phosphorus making 5 bonds with Phosphorus WebReasons for non-existence of [SiCl6]2−: (i) Due to smaller size of F, steric repulsions will be less in [SiF 6]2−. In [SiCl6]2−, six large chloride ions cannot be accommodated around Si4+ due to limitation of its size. (ii) Interaction between lone pair of fluoride with Si4+ is stronger while interaction between lone pair of chloride ion ... somers heath logo

WebSolution. Verified by Toppr. Due to smaller size of F as compared to Cl , six small F atoms can be easily accommodated around Si atom while Cl cannot. Since F are present in smaller 2p orbital and Cl are present in larger 3p orbital therefore interaction of F lone pair electron with d orbitals of silicon are stronger in F as compared Cl. WebMar 15, 2024 · The antenna consists of four substrate layers with relative permittivity ε r = 2.2 $\varepsilon _r = 2.2$ and their thickness is 0.508 mm, 0.508 mm, 0.254 mm, and 0.760 mm, sequentially from bottom to top. The antenna part is on the top of substrate 1, while the SICL feeding is integrated into substrate 2, substrate 3 and substrate 4. WebCBSE > Class 11 > Chemistry. in SiCl6 (2-) the chlorine atom is much larger than flourine which does not allow the six chlorines to surround the silicon due to repulsions between chlorine atoms. silicon cannot acomodate 6 chlorines around it. Hence , due to interelectron repulsions between chlorine atoms the compound SiCl6 (2-) is unstable and ... small cdl companies+manners
