Log in Join now 1. The hybridization theory is often seen as a long and confusing concept and it is a handy skill to be able to quickly determine if the atom is sp 3, sp 2 or sp without having to go through all the details of how the hybridization had happened.. Fortunately, there is a shortcut in doing this and in this post, I will try to summarize this in a few distinct steps that you need to follow. Answer: D 0 votes. One such compound is ethene, in which both carbon atoms make use of sp 2 hybrid orbitals. When Carbon gets a chance to form bonds with other atoms, mainly atoms of the p-block (Carbon, Hydrogen, Halogens, Oxygen, Nitrogen, etc., ) it excites one of the two electrons in the 2s atomic orbital of the ground state carbon atom to jump to the higher energy empty 2pz orbital. These sp 2 hybrid orbitals lie in a plane and are directed towards the corners of an equilateral triangle with a carbon atom in the centre. However, according to the answer given in the book, all carbon atoms in the smallest ester are $\mathrm{sp}^2$ hybridized. Lewis structure shown below.
