What is bond length of $\mathrm{C}-\mathrm{C}$ bond in alkane having all carbon atoms $\mathrm{sp}^{3}$ hybrid?
$154 \mathrm{pm}$
$133 \mathrm{pm}$
$112 \mathrm{pm}$
$120 \mathrm{pm}$
Solution
The carbon-carbon bond, with a bond length of $1.54 ~Ã…$, is formed by overlap of one $sp3$ orbital from each of the carbons, while the six carbon-hydrogen bonds are formed from overlaps between the remaining $sp3$ orbitals on the two carbons and the $1s$ orbitals of hydrogen atoms. All of these are sigma bonds.
