Electronegativity and acid strength of nonmetal hydrides
« on: September 22, 2010, 07:08:37 PM »
Okay, I'm reading in my book about how as electronegativity increases across a group, so does the acidity of the nonmetal hydrides...Which makes no sense to me. Isn't an acid stronger if it more easily gives up a proton (H+)? If it's more electronegative, doesn't that mean the nonmetal hydride is holding the hydrogen more strongly, meaning it doesn't as easily give up the proton? I mean electronegativity means "ability of an atom (or, more rarely, a functional group) to attract electrons (or electron density) towards itself," so I guess I must be understanding the definition wrong.

I'm so confused, so please somebody help me understand!

If electrons are attracted to the 'central' atom, is the proton attraction stronger, or weaker? Is the proton easier, or more difficult to remove?
