Arrange in the order of increasing acidic strength. 1. (CH3)2 CHOH 2. ...
Increasing acidic strength of the given compounds:1. CH3OH
CH3OH is a weak acid because it can donate a proton to form an ion, but it does not do so completely. Methanol is a weak acid because the carboxyl hydrogen (H) is held tight to the oxygen atom due to its electronegativity. So, it is the weakest acid among all.
2. (CH3)2CHOH
Secondary alcohols can donate protons but not as easily as primary alcohols. This is because the positive charge is not stabilized by resonance in secondary alcohols, making it less acidic than primary alcohols. Therefore, (CH3)2CHOH is less acidic than (CH3)3COH.
3. CH3CH2OH
Primary alcohols have a higher tendency to donate protons than secondary alcohols. The hydroxyl group (OH) is bound to a primary carbon atom in CH3CH2OH, making it a stronger acid than (CH3)2CHOH.
4. (CH3)3COH
Tertiary alcohols have the lowest acidity of all alcohols. The positive charge is not stabilized by resonance in tertiary alcohols, making them less acidic than primary and secondary alcohols. Therefore, (CH3)3COH is the least acidic among all.
5. H2O
H2O is not classified as an alcohol, but it can donate a proton to form an ion. Water is a weak acid because it can donate protons but does not do so completely, making it a stronger acid than all the alcohols mentioned above.
