Hybridisation is a method used in valence bond theory to create atomic orbitals of the correct symmetry for bonding. this is just a "model" of a chemical bond which happens to give very good predictions of molecular geometry. Hybridising s and p orbitas can produc sp hybrids, linear, sp2 hybrids, trigonal planar and sp3 hybrids, tetrahedral.
An alternative approcah to bonding is molecular orbital theory which models the bonds without necessarily hybridising the atomic orbitals first. This gives a more complex view of bonding that explains energy levels in the molecule but doesn't readily predit geometry. At the bottom both theories or models of cchemical bonds work out to be the same.

I disn't write whats below but it gives the rationalisation of valence bond theory but igmores MO theory which does work with the unhybridised orbitals.
You know the electrons are only present to counter balance the positive nucleus.If you consider an electron nearer to nucleus(1s electron) it is of low energy but as it goes far away(2s electron) its energy is higher because of higher potential energy. If you consider 1s orbital the shape is spherical just because if you try to locate an electron for a span of about 1 second it would be found anywhere around the nucleus in form of a sphere, thats why s orbitals are spherical same for 2s orbitals but since energy increases in 2p orbitals they are in dumb bell shaped lobes but when you loook at the lobe you may wonder how electron would have traveled from one lobe to another without passing the intermediate space thats associated with wave nature of electrons.When tow hydrogen atoms combine they can combine without any trouble because they have same energy orbitals.But when an carbon atom which has outer orbitals having 2 electrons in 2s orbital and 1 electron in 2px and 1 electron in 2py orbital cannot combine with hydrogen 1s orbitals because of unequal energies in 2s and 2p orbitals. In order to overcome this 2s and 2p orbitals combine and distribute their electrons in space such that all have equal energies. for example in methane after carbon undergoes sp3 hybridization that means a s orbital had combined with 3 p orbitals , and there are 4 lobes in sp3 hybrid each has an electron and they can now bond with hydrogen easily than an unhybridized atom
The hybridization of PCl3F2 is sp3d. This hybridization occurs when there are five electron domains around the central atom (phosphorus), consisting of three bonding pairs and two lone pairs.
Tetragonal hybridization is a type of hybridization in which one s and three p atomic orbitals mix to form four sp^3 orbitals oriented in a tetragonal arrangement. This hybridization occurs in molecules or ions with a central atom surrounded by four regions of electron density.
The hybridization of NCl3 is sp3.
The hybridization of Be in BeH2 is sp hybridization. Beryllium has 2 valence electrons and forms 2 bonds with the two hydrogen atoms in BeH2, resulting in sp hybridization.
The hybridization of the carbon atoms in an alkyne is sp.

To determine the hybridization of an atom from its Lewis structure, count the number of electron groups around the atom. The hybridization is determined by the number of electron groups, with each group representing a bond or lone pair. The hybridization can be identified using the following guidelines: If there are 2 electron groups, the hybridization is sp. If there are 3 electron groups, the hybridization is sp2. If there are 4 electron groups, the hybridization is sp3. If there are 5 electron groups, the hybridization is sp3d. If there are 6 electron groups, the hybridization is sp3d2.
The hybridization of N i n N2 is sp.
sp hybridization.
Dsp³ hybridization refers to a type of hybridization in which one d orbital, one s orbital, and three p orbitals combine to form five equivalent dsp³ hybrid orbitals. This hybridization typically occurs in transition metal complexes and results in a trigonal bipyramidal geometry, where three orbitals lie in a plane (equatorial) and two are oriented perpendicular to this plane (axial). It is commonly observed in molecules with coordination numbers of five, such as phosphorus pentachloride (PCl₅) and certain metal complexes.
To determine the hybridization of an atom in a molecule based on its Lewis structure, count the number of electron groups around the atom. The hybridization is determined by the number of electron groups, with each group representing a bond or lone pair. The hybridization can be determined using the following guidelines: 2 electron groups: sp hybridization 3 electron groups: sp2 hybridization 4 electron groups: sp3 hybridization 5 electron groups: sp3d hybridization 6 electron groups: sp3d2 hybridization
To determine the orbital hybridization of an atom in a molecule, you can look at the atom's steric number, which is the sum of the number of bonded atoms and lone pairs around the atom. The hybridization is determined by the steric number according to the following guidelines: Steric number 2: sp hybridization Steric number 3: sp2 hybridization Steric number 4: sp3 hybridization Steric number 5: sp3d hybridization Steric number 6: sp3d2 hybridization By identifying the steric number, you can determine the orbital hybridization of the atom in the molecule.
Two pi bonds are formed when sp2 hybridization occurs in ethene (C2H4). This is because each carbon atom forms a pi bond with the neighboring carbon atom, resulting in a double bond between the carbons.
