S + Px + Py + Pz are the four n=2 orbitals. These orbitals are not equal to threesided planar but they can be hybridized joining together the letter of S and P orbitals. As the outcomes, we get Sp2 orbitals. Also, these bonding now will be three sets of Sp2 orbitals expect for P orbitals has it didn’t include in the hybridization. Even more, these are cylindrically symmetrical sigma bonds as they combine with carbon sp2 and a hydrogen 1s orbital. The two carbon atoms of C1Sp2 and C1Sp2 can be linked together in resulting in the cylindrically symmetrical, they are named sigma bonds. Furthermore, the second bond among the carbon atoms can be defined as the combination of P orbitals on the single side of the carbon, likewise other side also contain
