The number of primary alcohols possible with the formula $C_4H_{10}O$ is :-

The adduct of the compound $'A'$ obtained by the reaction with excess of isopropyl magnesium iodide,upon hydrolysis gives a tertiary alcohol. The compound $'A'$ is

Absolute alcohol ($100\%$ alcohol) is prepared by distilling rectified spirit over:

Given below are two statements :
Statement $I$ :
In Lucas test,primary,secondary and tertiary alcohols are distinguished on the basis of their reactivity with conc. $HCl + ZnCl_{2}$,known as Lucas Reagent.
Statement $II$ :
Primary alcohols are most reactive and immediately produce turbidity at room temperature on reaction with Lucas Reagent.
In the light of the above statements,choose the most appropriate answer from the options given below :

An alcohol $X$ $(C_5H_{12}O)$ when reacted with conc. $HCl$ and anhydrous $ZnCl_2$ produces turbidity instantly. The alcohol $X$ can be prepared from which of the following reactions?

Give the structures of the products you would expect when each of the following alcohols reacts with $(a)$ $HCl - ZnCl_{2}$,$(b)$ $HBr$,and $(c)$ $SOCl_{2}$: $(i)$ $Butan-1-ol$,$(ii)$ $2-Methylbutan-2-ol$.
