Re: σ vs π bond tips thread
What do we need to know about the properties of sigma and pi bonds? I remember in class it had something to do with rotation, and that would break the pi bond, why would the rotation then not affect the sigma bond? Since a sigma bond consists of only 1 bond, it is able to rotate easily. However, pi...

One reason is because radicals have one odd electron that wants to be paired with another electron, so it'll take electrons from anything, including dna or amino acids.
