Answer 1

they are of 7 types
sp
sp2
sp3
dsp2
dsp3
d2sp3
d3sp3
its from my hand made notes

Answer 2

the process of an animal or plant breeding with an individual of another species or variety.

1.    Tetrahedral or sp3 Hybridization

The mixing of one 's' and three 'p' orbitals to form four equivalent hybrid orbitals is called sp3 hybridization. Due to mutual repulsion of electrons in these four orbitals, sp3 hybrid orbitals try to keep themselves as far away as possible from each other. The arrangement in space that keeps them farthest apart is that of a tetrahedron. Thus, the four hybrid orbitals are directed towards the four corners of a regular tetrahedron, making an angle of 109.50 with each other. Because of their tetrahedral orientation, this hybridization is also called tetrahedral hybridization.


2.     Triagonal or sp2 hybridization
  The mixing of one s & two p orbitals to form three new equivalent hybrid orbitals to form three new equivalent hybrid orbitals is called sp2 hybridization. The three hybrid orbitals lie in one plane, making an angle of 1200 with each other to avoid mutual repulsion.

3.    Diagonal or sp Hybridization
The mixing of one s and one p – orbital to form two equivalent hybrid orbitals is called sp hybridization. The hybrid orbitals lie as far apart as possible from each other to minimize the forces of repulsion. Hence, they point in opposite directions, making an angle of 1800.
