(A) (i) Define a homologous series of carbon compounds. (ii) Why is the melting and boiling points of C_4 H_8 higher than that of C_3 H_6 or C_2 H_4?…

Define a homologous series of carbon compounds.

Why is the melting and boiling points of $\displaystyle \mathrm{C}_{4} \mathrm{H}_{8}$ higher than that of $\displaystyle \mathrm{C}_{3} \mathrm{H}_{6}$ or $\displaystyle \mathrm{C}_{2} \mathrm{H}_{4}$ ?

Why do we NOT see any gradation in chemical properties of a homologous series compounds ?

Write the name and structures of (i) aldehyde and (ii) ketone with molecular form $\displaystyle \mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}$.

Write the name and structure of an organic compound 'X' having two carbon atoms in its molecule and its name is suffixed with '-ol'.

What happens when 'X' is heated with excess concentrated sulphuric acid at $\displaystyle 443$ K? Write chemical equation for the reaction stating the conditions for the reaction. Also state the role played by concentrated sulphuric acid in the reaction.

Name and draw the electron dot structure of hydrocarbon produced in the above reaction.
