Websp2 hybridization is observed when one s and two p orbitals of the same shell of an atom mix to form 3 equivalent orbitals. The new orbitals formed are called sp2 hybrid orbitals. sp 2 hybridization is also called trigonal hybridization. WebThe C-H bond stretching of all hydrocarbons occurs in the range of 2800–3300 cm-1, and the exact location can be used to distinguish between alkane, alkene and alkyne. …
