`(CH_(3))_(3)C-OH +HCI overset(Anhy.ZnCI_(2)+HCI)rarr`
`(CH_(3))_(3)C-CI +H_(2)O3^(@)` reacts immediately
`(CH_(3))_(3)Ch-OH+HCI overset(Anhyd.ZnCI_(2)+HCI)rarr`
`(CH_(3))_(2)CH-CI+H_(2)O2^(@)` reacts after `5` min
`CH_(3)CH_(2)CH_(2)-OH +HCI overset(Anhyd.ZnCI_(2)+HCI)rarr`
`CH_(3)CH_(2)CH_(2)-CI +H_(2)O1^(@)` reacts only on heating.
