$CH_3 CH_2 OH$ $\xrightarrow{Cl_2} CH_3 CHO$ $\xrightarrow{3 Cl_2} Cl_3 CCHO$. In the above reactions,the role of $Cl_2$ in step-$1$ and step-$2$ respectively is:

$CH_3-CH(OH)-CH_3$ $\xrightarrow{PBr_3}$ $A$ $\xrightarrow{Mg}$ $B$ $\xrightarrow{\text{Oxirane}}$ $C$ $\xrightarrow{H_2O}$ $D$. Here,$D$ is

Which is the best method to prepare cycloalkene from cyclohexanol?

In the given reaction,find the value of $x$,where $x$ is the number of moles of acetic anhydride $(Ac_2O)$ consumed.

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:

Which of the following is most soluble in water?
