Question

- The highest bond length will be observed in - fon :- (1) C-H (2) C-N (3)C-C (4) C-O​

Answer 1

The highest bond length is present in the (3) C-C.

• The bond length is higher in the compounds when the bonds are weaker, and the bond length is lower in the compounds when bonds are stronger.
• C-H bonds are about 20% stronger than C-C bonds.
• Since hydrogen, having only one electron shell, is much smaller than carbon, the distance between the nuclei is shorter, there is a greater force of attraction to the density of electrons in between.
