The carbon anion contains only three bonds, before it takes the electron for its charge. Orbitals with a single electron do not hybridize.
In propenoic acid (also known as acrylic acid), the carbon-carbon double bond and the carbonyl group result in sp2 hybridization for both carbon atoms in the double bond and the carbonyl carbon. The oxygen atom in the carbonyl group has sp2 hybridization, while the remaining carbon atoms have sp3 hybridization.
The carbon atom in carbon dioxide is sp2 hybridized. This means that there are three electron pairs around the carbon atom, resulting in trigonal planar geometry.
The nitrogen atom of pyridine is sp2 hybridized. It participates in the aromatic ring system of pyridine and forms three sigma bonds with neighboring carbon atoms, resulting in the sp2 hybridization.
The central carbon atom in CO2 has a hybridization of sp2. This means that the carbon atom uses one s orbital and two p orbitals to form three sp2 hybrid orbitals for bonding.
the hybrdization of allyl radical carbon is sp2 which overlaps with the p orbitals of the alkene
The carbon atoms are sp2 hybridised.

The C in h3c is sp3 hybridized The c in ch is sp2 hybridized the c in ch2 is sp2 hybridized

The carbon atom in a carboxylic acid molecule is sp2 hybridized.
In an alkene, the carbon is sp2 hybridized (trigonal planar with 120° bond angles), while in an aromatic ring, the carbon is sp2 hybridized due to resonance. Therefore, a carbon in a molecule with both alkene and aromatic functional groups would also be sp2 hybridized.
Prsumably you mean AlH4- the tetrahydroaluminate anion. The hybridization of the central atom of AlH4 is sp3.
sp2
Carbon rehybridizes from sp3 to sp2 in tin chemistry due to the formation of a coordinate covalent bond between carbon and tin. This leads to the promotion of one electron from a lone pair orbital on carbon to form a π bond with tin, requiring the carbon to undergo sp3 to sp2 hybridization to accommodate the new bonding situation.
