Understanding the terminology and geometries of hybridized orbitals (part of the valence bond theory). Which has trigonal planar shape? Trigonal planar and trigonal pyramidal are two geometries we use to name the three dimensional arrangement of atoms of a molecule in the space. The trigonal planar structure consists of the sp2 type of hybridization. sp hybridization is observed when one s and one p orbital in the same main shell of an atom mix to form two new equivalent orbitals. The pairs are arranged along the central atom’s equator, with 120° angles between them. If the double bond was instead a single bond, with the other being a lone pair, then it would have been trigonal pyramidal. SURVEY .

In organic chemistry, planar, three-connected carbon centers that are trigonal planar are often described as having sp2 hybridization.[2][3]. All the three hybrid orbitals remain in one plane and make an angle of 120° with one another. Due to the spherical shape of s orbital, it is attracted evenly by the nucleus from all directions. sp2 hybridization is observed when one s and two p orbitals of the same shell of an atom mix to form 3 equivalent orbital. Such species belong to the point group D3h. When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp3. Since there is also some kind of repulsion present in the molecule due to a lone pair. Hence, the sp hybridized carbon is more electronegative than sp2 and sp3. Also, the orbital overlap minimizes the energy of the molecule. It's a flat planar molecule except for the H atoms in the CH3 group - H atoms can be in the plane , above the plane, or below the plane as the CH3 group can rotate relative to the plane.
