The carbanion is sp3-hybridized. This means that the carbon atom has formed four sigma bonds, with three of them being single bonds and one being a lone pair. This results in the carbon atom having a tetrahedral geometry with bond angles of approximately 109.5 degrees. **

Electronegativity is the ability of an atom to attract shared electrons in a covalent bond. In sp hybridization, the electronegativity is determined by the electronegativities of the two atoms involved in the bond. In sp2 hybridization, the electronegativity is also determined by the electronegativities of the atoms involved, but the presence of the additional p orbital can affect the distribution of electron density. In sp3 hybridization, the electronegativity is again determined by the electronegativities of the atoms involved, but the presence of three p orbitals can further affect the distribution of electron density. Overall, the electronegativity in sp, sp2, and sp3 hybridizations is determined by the specific atoms involved and the overall electronic structure of the molecule. **

No, not all molecules with an sp2-hybridized carbon atom are planar. While sp2 hybridization does result in a trigonal planar geometry, the presence of other atoms or groups around the carbon atom can cause the molecule to deviate from a perfectly planar shape. For example, the presence of bulky substituents or lone pairs of electrons can introduce steric hindrance and cause the molecule to adopt a non-planar conformation. Additionally, the presence of double bonds or aromatic rings can also lead to non-planar geometries due to the constraints imposed by the pi-bonds. **

In chemistry, sp3 and sp2 orbitals are hybrid orbitals formed by the combination of s and p orbitals. The main difference between sp3 and sp2 orbitals lies in their geometry and the number of p orbitals involved in the hybridization. Sp3 orbitals are formed by the combination of one s and three p orbitals, resulting in a tetrahedral geometry, while sp2 orbitals are formed by the combination of one s and two p orbitals, resulting in a trigonal planar geometry. Additionally, sp3 orbitals have 25% s character and 75% p character, while sp2 orbitals have 33.3% s character and 66.7% p character. **

One can determine the hybridization of an atom by looking at the number of electron groups around the atom. For example, if an atom has 2 electron groups (2 bonds and 0 lone pairs), it will be sp hybridized. If it has 3 electron groups (3 bonds and 0 lone pairs), it will be sp2 hybridized. And if it has 4 electron groups (4 bonds and 0 lone pairs), it will be sp3 hybridized. This is based on the concept that hybridization allows atoms to achieve the most stable electron configuration by maximizing bonding opportunities. **
