A) \[{{H}_{2}}S{{O}_{4}}+HCl\]
B) \[Mn{{O}_{2}}+{{H}_{2}}S{{O}_{4}}\]
C) \[ZnC{{l}_{2}}+conc.\text{ }HCl\]
D) \[ZnC{{l}_{2}}+conc.\text{ }{{H}_{2}}S{{O}_{4}}\]
Correct Answer: C
Solution :
Lucas's reagent is \[ZnC{{l}_{2}}+conc.\,HCl\]it is used to differentiate between p, s, and t ?alcohol \[ROH+HCl\xrightarrow{ZnC{{l}_{2}}}RCl+{{H}_{2}}O\] If cloudiness appears immediately \[\to \] t-alc If cloudiness appears after 5 min \[\to \] s-alc If cloudiness appears only on heating \[\to \] p alcYou need to login to perform this action.
