Which of the following is $NOT$ produced by the reaction of ethanol with $H_2SO_4$?

The alcohol that produces turbidity immediately with $ZnCl_2 +$ conc. $HCl$ at room temperature is:

An unknown alcohol is treated with the "Lucas reagent" to determine whether the alcohol is primary,secondary,or tertiary. Which alcohol reacts fastest and by what mechanism?

Consider the following alcohols:
$(I)$ $C_6H_5CH_2OH$
$(II)$ $O_2N-C_6H_4-CH_2OH$ (para-nitro)
$(III)$ $CH_3O-C_6H_4-CH_2OH$ (para-methoxy)
$(IV)$ $Br-C_6H_4-CH_2OH$ (para-bromo)
The order of decreasing reactivities of these alcohols towards nucleophilic substitution with $HBr$ is:

Which of the following alcohols is used in beverages?

Isopropyl alcohol heated at $300\,^{\circ}C$ with a copper catalyst forms:
