Homework Help: Chemistry nomenclature help

  1. Aug 29, 2010 #1
    1. The problem statement, all variables and given/known data

    my book says that for nonmetal binary compounds that like

    you name the first element first than the next element with the proper prefix indicating how many atoms there are of that element

    Carbon monoxide

    Makes sense but it also says no prefixes are used for hydrogen... I'm not really sure what this means can someone give me an example like


    if it even exists and how you would name it would it just be the name of the first element then hydrogen regardless of the subscript on the bottom of the H

    2. Relevant equations

    3. The attempt at a solution

    probably carbon hydrate

    CH isn't really anything. The hydrogen thing is strange, most molecules will have hydrogen as the cation, which usually goes on the left (H2O, H2O2, HCO3...). If hydrogen is an anion (has a negative charge), it is usually called a hydride.

    So, CH would be carbon hydride, NaH would be Sodium Hydride, and so on.
