Arrange the following single bonds in increasing order of their bond lengths: . — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Bond length decreases with higher bond order (multiple bonds) and smaller atomic radii. $C-H$ is shortest due to H's tiny size, followed by the double bond $C=C$, then the polar single bond $C-O$, and finally the non-polar single $C-C$ bond.
