The order of reactivity of following alcohols with halogen acids is ……… (A) CH_(3)CH_(2)-CH_(2)-OH(B)CH_(3)CH_(2)-underset(CH_(3))underset("|")("C ")H-OH(C ) CH_(3)CH_(2)-overset(CH_(3))overset("|")underset(CH_(3))underset("|")("C")-OH

Answer»

`(A)gt (B)gt (C )`
`(C )gt (B)gt (A)`
`(B)gt (A)gt (C )`
`(A)gt (C )gt (B)`

SOLUTION :The reaction of HALOGEN acids with alcohol procceeds through carbocation intermediate. Greater stability of Carbocation, FASTER is the reaction. The stability order is `3^(@)gt 2^(@)gt 1^(@)`.
