ΣH adducts

  1. What is a σH adduct? I understand what an adduct is, I am just not sure what the σH is referring to. I could take a few wild guesses; but I've learned that going "John Wayne" doesn't always lead to the the correct answer. (Its cool looking, but not very effective...)

    Thanks!

    "The product formed by the attachment of an electrophilic or nucleophilic entering group or of a radical to a ring carbon of an aromatic species so that a new sigma bond is formed and the original conjugation is disrupted."

    From "IUPAC Compendium of Chemical Terminology."
     
  4. What about σD adducts? Where does the H and D superscripts come from?

    H is hydrogen. Can you tell what D might be?
     
  6. According to me D stands for density and this is what I know as, these are the things that comes in chemical terms and they are used for all the equations that are always used.


    Thanks!

    No, D doesn't stand for density here.

    Hint: T doesn't stand for time :wink:
