Why are detergents better cleansing agents than soaps? Explain.

In which of the following compounds,$-OH$ is the functional group?

Draw the electron dot structure of ethane,$C_{2}H_{6}$.

Which condensation polymer is formed from hexamethylenediamine and adipic acid?

What is saponification? Write the reaction involved in this process.

An organic compound $A$ on heating with concentrated $H_2SO_4$ forms a compound $B$, which on addition of one mole of hydrogen in the presence of $Ni$ forms a compound $C$. One mole of compound $C$ on combustion forms two moles of $CO_2$ and $3$ moles of $H_2O$. Identify the compounds $A$, $B$, and $C$ and write the chemical equations of the reactions involved.
