What is the order of acidic character of primary, secondary and tertiary alcohols? |
Answer» Solution :The `1^(@),2^(@) and 3^(@)` alcohols have one, two and three alkyl groups on the CARBON atom attached to the OH group as shown below:  Since alkyl groups have +I-effect, therefore, electron density in O-H bond INCREASES from `1^(@)` to `3^(@)` alcohols. In other WORDS, the O-H bond in `3^(@)` alcohols is the strongest and hence most difficitul to break followed by O-H bond in `2^(@)` alcohols while the O-H bond in `1^(@)` alcohols is the weakest and hence most easy to break. THUS, the acid STRENGTH of alcohols follows the order: primarygtsecondarygttertiary. |
