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 are shorter) and smaller atomic radii (H is very small). Thus, $C-H$ is shortest, followed by the double bond $C=C$, then the polar single bond $C-O$, and finally the non-polar $C-C$.
