The decreasing order of acidity among following compounds, ethanol (I), 2, 3, 2-trifluoroethanol (II), the fluoroacetic acid (III) and acetic acid (IV) is

The decreasing order of acidity among following compounds, ethanol (I)

1.	The decreasing order of acidity among following compounds, ethanol (I), 2, 3, 2-trifluoroethanol (II), the fluoroacetic acid (III) and acetic acid (IV) is
Answer» `III gt II gt IV gt I` `IV gt III gt II gt I` `I gt II gt III gt IV` `III gt IV gt II gt I` Solution :Carboxylic ACIDS are stronger acids than alcohols and fluoroacids are stronger acids than the substituted acids and fluoro alcohols are stronger than unsubsituted alcohols. This acidity DECREASES in the ORDER trifluoro acetic acid (III), `gt` acetic acid IV `gt` trifluoro ethanol `gt` ethanol
