Determine the molecular structure abs hybridization of the central atoms X in the poly atomic ion XY3 + given that a neutral X atom contains 36 electrons and Y makes an anion with a -1 charge, which has the electron configuration of 1s^22s^22p^6
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
Determine the molecular structure abs hybridization of the central atoms X in the poly atomic ion XY3 + given that a neutral X atom contains 36 electrons and Y makes an anion with a -1 charge, which has the electron configuration of 1s^22s^22p^6
The ion given is XY3+ where X is the element with number of electrons 36 in neutral atom and Y forms an ion with -1 charge.
Since the atomic number of a neutral element = number of electrons = 36
Since the element with 36 atomic number is Krypton i.e Kr. Hence X is Kr.
Since Y is forming anion with -1 charge having electron configuration = 1s22s22p6
Hence the number of electrons in neutral atom of Y = number of electrons in electron configuration of Y-1 + charge on anion
=> number of electrons in neutral atom of Y = (2 + 2 + 6 ) + (-1) = 9
Hence the atomic number of Y = 9
Since the atomic number 9 is of Fluorine atom i.e F. Hence Y is F.
