Arrange the following compounds in order of increasing Boiling point: CH4, CHCl3, CCl4, CH3Cl

Try this. The higher boiling point often is the compound with the higher molar mass.

CCl4 is the highEST boiling point which means CCl4 should be at the top. CH4 has the lowest b.p. so it should be at the bottom.

CH4.....(CHCl3/CH3Cl).....CCl4.
So place CHCl3 and CH3Cl in the proper order to make it increasing b.p. from CH4 to CCl4.

To determine the order of increasing boiling point, we need to consider the intermolecular forces present in each compound. The strength of intermolecular forces affects the boiling point, with stronger intermolecular forces resulting in higher boiling points.

1. CH4 (methane): Methane is a nonpolar molecule. It exhibits only weak London dispersion forces between its molecules due to the temporary shifts in electron density. These forces are the weakest intermolecular forces. Therefore, CH4 has the lowest boiling point among the given compounds.

2. CHCl3 (chloroform): Chloroform is a polar molecule. It has a dipole moment due to the electronegativity difference between carbon and chlorine atoms. Chloroform molecules experience dipole-dipole interactions, which are stronger than London dispersion forces. Therefore, CHCl3 has a higher boiling point than CH4.

3. CH3Cl (methyl chloride): Methyl chloride is also a polar molecule. It has a slight dipole moment due to the electronegativity difference between carbon and hydrogen atoms. Similar to chloroform, methyl chloride molecules experience dipole-dipole interactions, which are stronger than London dispersion forces. As a result, CH3Cl has a higher boiling point than CH4 but lower than CHCl3.

4. CCl4 (carbon tetrachloride): Carbon tetrachloride is a nonpolar molecule. It has four symmetrically arranged chlorine atoms around the central carbon atom, resulting in a net dipole moment of zero. Similar to methane, CCl4 experiences only weak London dispersion forces between its molecules. Thus, CCl4 has the highest boiling point among the given compounds due to the larger size and greater molecular weight compared to the other compounds.

Therefore, the order of increasing boiling point is:
CH4 < CH3Cl < CHCl3 < CCl4

CCL4 has the higher boiling point?
