The reaction of $4-(\text{aminomethyl})\text{cyclohexylmethanol}$ with acetic anhydride $(Ac_2O)$ proceeds in two steps to form $P$ and $Q$. Identify $P$ and $Q$ respectively.

What is the product '$A$' in the following reaction?
(Image of an epoxide ring fused to a cyclopentane ring with an exocyclic double bond,reacting with $H_3O^{\oplus}$ to form $A$.)

Write about the oxidation of alcohols.

$A$ toxic compound $A$ when reacted with $NaCN$ in aqueous acidic medium yields an edible cooking component and food preservative $B$. $B$ is converted to $C$ by diborane and can be used as an additive to petrol to reduce emission. $C$ upon reaction with oleum at $140^{\circ} C$ yields an inhalable anesthetic $D$. Identify $A, B, C$ and $D$,respectively.

How many isomers of ${C_5}{H_{11}}OH$ are primary alcohols?

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 :
