Arrange the following alchols in the decreasing order of their reactivity with `HRr` :
(1) `C_6 H_5CH_2OH`
(2) `(C_6H_5)_2 CHOH`
(3) `(C_6H_5)_3 COH`

Text Solution

AI Generated Solution

To arrange the given alcohols in decreasing order of their reactivity with HBr, we need to consider the stability of the carbocations that will form during the reaction. The stability of carbocations is influenced by the number of alkyl groups attached to the positively charged carbon atom and the electron-donating or withdrawing effects of substituents. ### Step-by-Step Solution: 1. **Identify the Alcohols**: - (1) `C6H5CH2OH` (Benzyl alcohol) - (2) `(C6H5)2CHOH` (Diphenylcarbinol) - (3) `(C6H5)3COH` (Triphenylcarbinol) ...
