Webb31 juli 2024 · For ethene, there is no rotation about the carbon-carbon double bond because of the pi bond. Can free rotation occur about a single bond? We learned in section 2.1 that single bonds in organic molecules are free to rotate, due to the ‘end-to-end’ (sigma) nature of their orbital overlap.
