How many of the following molecules contain at least one pi bond? C 2 H 6 Cl 2 CO C 2 Cl 4 HCN

Hello. In this problem, we are asked based on the structure below to determine the number of pi bonds present in a Listerine, A single bond he's made up of a sigma bond and a double bond Contains 1 σ bond, one pi bond. So to determine the number of pi bonds, we need to count up the number of double bonds, so we have double bonds, so that means that we have eight pythons. This then corresponds to answer C. Thanks for watching. Hope. This helped.
