At the Family Tree DNA Conference in November, James Irvine and Maurice Gleeson both presented sessions on utilizing a combination of STR and SNP data and various tools in analyzing their individual projects. Mauriceâs presentation was titled âCombining SNPs, STRs and Genealogy to build a Surname Origins Tree.â.
SO4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds. These single bonds are shorter than normal sulfur-oxygen single bonds but longer than a sulfur-oxygen carbon bond. This phenomenon is called resonance. C) SF6 has entirely covalent sulfur-fluorine bonds and is octahedral.D) CaI2 is an ionic compound, with the calcium and iodide ions in a lattice structure.O4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds.

Answer by Zosimus. Confidence votes 7.2K. AlCl3 has simple covalent bonding because the aluminium cation is so small and highly charged (3+) that it has an extremely high charge density. This charge density distorts the electron cloud of the anions (Cl-) to such a large degree that the bonding is considered as covalent.This is why AlCl3 vapourises at room temperature, because it only has weak van der waal's intermolecular forces.luminum chloride is an ionic compound because aluminum is a metal and chlorine is a nonmetal. The combination of a metal bonded with a nonmetal is an ionic compound. Incorr â¦ ect. Aluminium Chloride is covalent.
