Shortcut to find Hybridisation - Chemistry Tip!!
  • 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
