Hydrogen bond

  1. Dec 3, 2016 #1
    can H2s form hydrogen bonds
    i read that H2s can , but i'm not so sure about it .

    No such thing as H2s, I assume you mean H2S.

    Why do you think it can't?

    yes , sorry i meant H2S , to my mind that hydrogen bond only exist between hydrogen bond with N or O or F .

    What is your rationale behind limiting hydrogen bonds to these three elements?
     
  6. Dec 3, 2016 #5
    because our teacher used to teach us that the hydrogen bond only come with N , O , F.

    Then i have read that H2S can form hydrogen bond .

    Do you still have the same teacher, or have you progressed/advanced?

    The same teacher it will never change until you graduate from the high school .

    but i want to know is H2S can make hydrogen bond

    Think about what the hydrogen bond really is. What bonds with what and how.

    You do know that all bonds are in fact "just" electrostatic attractions between charges?

    hydrogen bond is a type of intermolecular force that exist when hydrogen atom compound with
    1 -a high electronegativity atom such as N,O,F .
    2-it also must be a small atom .
    3- when it compound with hydrogen it must have at least one free pair of electron .

    One of the problems is that a there is no sharp border between weak hydrogen bonds and van der Waals interactions.
    Fact is that the SHS interaction is much smaller than e.g. the OHO interaction in water. Whether you call it a hydrogen bond or not may be a matter of convention.

    Reading the original question again, I think it is important to distinguish further to what extent H2S can act as hydrogen bond donator versus acceptor.
