Nitrogen, oxygen, and chlorine:
In an organic structures Nitrogen, oxygen and chlorine atoms can as well be sp3 hybridized. Nitrogen contains five valence electrons in the second shell of it. Later than the hybridization, it will have 3 half-filled sp3 orbitals and can make three bonds. Oxygen comprises six valence electrons. Later than the hybridization, it will comprise two half-?lled sp3 orbitals and will make two bonds. Chlorine contains 7 valence electrons. After hybridization, it will contain one half- filled sp3 orbital and will make one bond.
The four sp3 orbitals for these three atoms create a tetrahedral arrangement along with one or more of the orbitals occupied through a lone pair of electrons. Referring the atoms alone, nitrogen creates a pyramidal shape in which the bond angles are little less than 109.5o (c. 107o). This compression of the bond angles is because of the orbital consisting of the lone pair of electrons that demands a little greater amount of space than a bond. Oxygen creates an angled or bent shape in which two lone pairs of electrons compress the bond angle from 109.5o to c. 104o.
