Question
Arrange the following compounds in decreasing order of acidity.
\[\ce{H2O, ROH, HC ≡ CH}\]
Advertisements
Solution
The decreasing order of the acidity of the given compounds:
\[\ce{H2O > ROH > HC ≡ CH}\]
\[\ce{HC ≡ CH}\] is less acidic because the carbon atoms here is sp hybridized, so the electron density is higher on the carbon atom.
