Im not sure where to factor in the two longer compounds for this problem.
"Rank the given compounds based ontheir relative acidities"
This is the order i thought it was, but this isnt right apparently...
(--- means triple bond, -- means double bond)
You didn't post the order you thought was correct. And the problem doesn't say increasing acidity or decreasing acidity.
From least acid to most acid.
H atoms on double and triple bonded carbon are acidic, triple bonds always moreso than double bonded C.
okay thanks but that was wrong actually
Sorry about that. I mixed up the NH3 and CH4
As a series, they go across the periodic table like this.
CH4 NH3 H2O HF with HF being the most acid and CH4 the least acid. Actually, I typed it that way the first time but the computer didn't post it and when I redid it I screwed up.
