-The geometries of both carbon atoms in the given molecule are triangular planar, which is a planar geometry, and the shape is also the same.
ethene. The simplest alkeneethene (H2C=CH2) is planar with H-C-H and H-C-C bond angles close to 120°. Figure 8.2 These 120° bond angles and planar geometry are consistent with the sp2 hybridization for each of the ethene C atoms (Chapter 1).
4. Shapes: CH3 groups are tetrahedral, the other C atom is trigonal planar.
O2 is a non-polar molecule with linear geometry. There are four lone pairs of electrons in the oxygen molecule.
Methane has a tetrahedral molecular geometry and is therefore a tetrahedral molecule.
C2H2 has a linear molecular geometry because all the atoms are symmetrically aligned in the same plane. Both carbon atoms are at the center of the C2H2 Lewis structure because they are less electronegative than hydrogen atoms.
Carbon dioxide is linear while sulfur dioxide is curved (V-shaped). In carbon dioxide, the two double bonds try to get as far apart as possible, and so the molecule is linear.
What is the structure and hybridization of CH3-? Tetrahedron – the hybridization of one s and three p orbitals creates four hybrid orbitals aligned to the points of a regular tetrahedron, 109.5° 109.5° apart. CH3 (methyl free radical) has a planar structure with sp2 hybridization of the ‘C’ atom.
As we can see in the VSEPR diagram above, we have a curved molecular geometry for NH2-. It has a bond angle of 104.50, much less than the general ideal of 109.50. This is due to the strong repulsion of the two lone pairs of electrons on the central N atom.
CH3• is planar because of steric repulsion from H−H.
The oxygen molecule lies under the umbrella of the diatomic molecule. Therefore, it forms a linear geometric structure and both oxygen atoms have the same electronegativity and other properties.
Most organic molecules, including all alkanes, are not planar but are characterized by three-dimensional structures. For example, methane has the shape of a regular tetrahedron with carbon in the center and a hydrogen atom at each corner.
Therefore, according to the VSEPR theory, the water molecule achieves a curved or V-shape pair repulsions due to the presence of lone pair lone pair, lone pair bond pair and bond pair bond. So the answer is V-shape.
