Explanation / Answer

3. Arranging molecules in increasing order of IMF

a. N2 < I2 < H2S < H2O6

H2O6 is cluster of water, which forms strong H-bonds. H2S also forms H-bonds but S is less electronegative and thus lesser extent of bonding. I2 has london dispersion which is greater than smaller molecule as N2.

b. H2Po < H2Te < H2Se < H2S

As the basicity of atoms decreases in the order S to Po, the extent of H-bonding also reduces.

4. CH3CH2CH3CH3CH2CH3 < CH3OCH3CH3OCH3 < CH3CH2OHCH3CH2OH

alcohols can form strong H-bond and this increases its boiling point. Hydrocarbons as first entry only has weak london dispersion forces which is why it has lowest boiling point. Ethers have greater amount of polar-polar interacton and london dispersion forces compared to hydrocarbon.

b. Cl2 < Br2 < I2

As the size increases from the Cl2 to I2, the surface area for intermolecular forces also increases, which increases the boiling point of molecules.
