$R-OH + HX \to R-X + H_2O$. In the above reaction,the reactivity of different alcohols is:

What are $X$ and $Y$ in the following reactions?

$n$-Propyl alcohol and isopropyl alcohol can be chemically distinguished by which of the following reagents?

The reaction $CH_3-C(CH_3)(OH)-CH_3 \xrightarrow{H_2SO_4} CH_3-C(CH_3)=CH_2$ is an example of:

An organic liquid $A$ containing $C$,$H$,and $O$ has a pleasant odour with a boiling point of $78\ ^\circ C$. On boiling $A$ with conc. $H_2SO_4$,a colourless gas is produced which decolourises bromine water and alkaline $KMnO_4$. One mole of this gas also reacts with one mole of $H_2$. The organic liquid $A$ is:

Identify the organic product formed when ethylene glycol is heated with acidic potassium permanganate $(KMnO_4)$.
