By clicking Accept All, you consent to the use of ALL the cookies. The atomic number of Carbon is 6 so 2 electrons are filled in s orbital and the rest 4 are in the outer orbital that is why the valence number of electrons in carbon is 4. Carbon is bonded with H and N both so needs only two sigma bonds which are provided by two sp orbitals. The linear molecular geometry of hydrogen cyanide has bond angles of 180 degrees.Because hydrogen and nitrogen tend to be far apart, HCN takes on a linear structure.Because of its electronegative value, nitrogen seeks to attract electrons to itself, making it somewhat polar.As a result of these changes, as the vector moves from hydrogen to nitrogen, hydrogen will have slightly positive charges and nitrogen will have slightly negative charges.As a result, the nitrogen atom becomes a negative pole and the hydrogen atom becomes a positive pole, resulting in a polar molecular structure. The C and N atoms present in the HCN molecule are sp hybridized. In this blog post, we are going to look at its hybridization that can help us understand its chemical and physical properties. So, one electron of CN may react with the one electron of hydrogen present in the valance orbital. If we discuss the electronic configuration of carbon and nitrogen. Hydrogen has only one electron in its outermost shell. On both sides of the central sulfur atom in the H2S Lewis structure, there are two hydrogen atoms. Steric number = number of atoms attached to the central atom + number of lone pairs. CO,2. C = Cationic charge. So the hybridization for HCN molecule is sp hybridization.
