the bonding between the carban and the nitrogen in hydrogen cyanide or hydrocyanic acid is a triple bond, hence the hybrid orbital is sp, due to the linear geometry of the molecule
The central atom of ammonia is nitrogen and it has 3 bonding pairs and a lone pair around, hence it undergoes sp3 hybridization. The central atom of boron trifluoride is the boron atom, and around it has only three bonding pairs. So it hybridizes as sp2.
To predict the hybridization of the central atom in a molecule or ion, you can use the formula: hybridization = (number of valence electrons on central atom + number of monovalent atoms attached to the central atom - charge)/2. This will give you the approximate hybridization state of the central atom based on the number of regions of electron density around it.
In carbon monoxide (CO), the carbon atom exhibits a hybridization state of sp. This is due to the formation of a triple bond between carbon and oxygen, which involves one sigma bond and two pi bonds. The sp hybridization occurs because one s orbital and one p orbital from carbon combine to form two equivalent sp hybrid orbitals, allowing for the linear arrangement of the molecule.
Fe(CN)₂ is composed of iron (Fe) ions and cyanide (CN) ions. In this compound, iron typically has a +2 oxidation state, making it a ferrous ion (Fe²⁺), while each cyanide ion carries a -1 charge. Therefore, the overall structure consists of one Fe²⁺ ion and two CN⁻ ions.
The compound name for Fe(CN)₃ is iron(III) cyanide. In this compound, iron has a +3 oxidation state, which is indicated by the Roman numeral III in the name. The cyanide ion (CN⁻) acts as a ligand, and since there are three of them, it forms a coordination complex with the iron ion.
The hybridization state of each carbon atom in nemotin is sp3.
The hybridization state for SiH3 is sp3, which means that the silicon atom is bonded to three hydrogen atoms using four sp3 hybridized orbitals.
The hybridization state of Al in AlH4- is sp3, as it has four electron groups around the central aluminum atom. This leads to the formation of four sigma bonds, resulting in tetrahedral geometry.
The hybridization state of Se in SeCl2 is sp^3 because it has two bonding pairs and two lone pairs around the selenium atom, leading to a tetrahedral electron geometry.
The hybridization state of SiBr4 is sp3 (tetrahedral). Silicon has 4 valence electrons, and in SiBr4, these electrons form 4 sigma bonds with the bromine atoms, resulting in a tetrahedral geometry.

The empire state building is larger by far.
The hybridization of NCl3 is sp3.
The central atom of ammonia is nitrogen and it has 3 bonding pairs and a lone pair around, hence it undergoes sp3 hybridization. The central atom of boron trifluoride is the boron atom, and around it has only three bonding pairs. So it hybridizes as sp2.
