Tricks to find
bond:
Calculation of σ-bonds (S):
Formula number 1 for σ-bonds (S): J+N-1
Where,
S= Total number of sigma bond
J= Total number of hydrogen atoms
N= Total number of carbon atoms
Note: This formula is applicable for simple open
chain unsaturated hydrocarbon
Example :
1. C176H250
S= 250+176-1 = 425
2. C2H4
S= 4+2-1 = 5
Formula
number 2: σ-bonds (S):
S= Number of atoms other than C + (number of C
atom -1)
Note: This formula is applicable for simple open
chain unsaturated hydrocarbon and their derivatives.
Example:
1. C6N4
S= 4+ (6-1) = 9
Please give the post to find No of pi bond
ReplyDeletePlease tell how can we calculate sigma bond from just condensed formula form???
