shortcut way to find hybridisation

Chemistry , Inorganic Chemistry

1st step    : count the no. of valence electrons[ V ]
2nd step   :   now divide V by 8 ,if V >8
or
divide V by 2 ,if V <=8             -[1]
if the remainder is still not zero then
again divide it by 2,                                       - [2]
therefore the final value = quotient in 1+ quotient in 2
as    shown in the example
3rd step    : compare the above obtained value with the table given below :-
sp    -   2
sp2        -   3
sp3        -   4
sp3d      - 5
sp3d2    -   6
sp3d3    -   7
ex:- for c2h6
step 1   -   2[4 ] + 6[1] = 4+6=10
step 2    -   as 14>8
14/8, quotient=1 as remainder = 6 which is not equal to zero
therefore 6 / 2   quotient=3
therefore final value=1+3=4
comparing with the table given above
the hybridisation is sp3.
note - this is not applicable to all compounds

It is insufficient to mention that this method is not applicable to all compounds instead u wud hav stated to which compounds it is applicable.
