1.

Which of the following alcohols will yield the corresponding alkyl chlride on reaction with concentrated HCl at room temperature ?

Answer»

`CH_(3)CH_(2)-CH_(2)-OH`
`CH_(3)CH_(2)-underset(CH_(3))underset("|")("C ")H-OH`
`CH_(3)CH_(2)-underset(CH_(3))underset("|")("C ")H-CH_(2)OH`
`CH_(3)CH_(2)-overset(CH_(3))overset("|")underset(CH_(3))underset("| ")("C")-OH`

SOLUTION :`3^(@)` alcohols are more reactive TOWARDS HCl because of formation of `3^(@)` CARBOCATION whereas, the reaction of `1^(@)` and `2^(@)` alcohol with HCl requires catalyst.
