What would the boiling point of sulphur Hexachloride be? I am doing a study of it and there is a question about whether SCl6 has a higher boiling point than NH3... please help i need it urgently
To determine the boiling point of sulfur hexachloride (SCl6), it is important to consider the intermolecular forces between its molecules. The boiling point depends on those forces.
To compare the boiling points of SCl6 and NH3 (ammonia), we need to examine their molecular structures and the intermolecular forces present in each compound:
1. Sulfur hexachloride (SCl6) is an inorganic compound that consists of a central sulfur atom bonded to six chlorine atoms. It forms a trigonal prismatic shape with a symmetrical distribution of charge.
2. Ammonia (NH3) consists of a central nitrogen atom bonded to three hydrogen atoms. The molecule has a pyramidal shape, with an uneven distribution of charge.
Now let's consider the intermolecular forces that affect boiling points:
1. Van der Waals forces: SCl6 molecules contain both polar covalent bonds (due to the electronegativity difference between sulfur and chlorine) and molecular polarity. These lead to a dipole-dipole interaction between SCl6 molecules, which is stronger than the dispersion forces present in NH3.
2. Hydrogen bonding: NH3 exhibits hydrogen bonding due to the presence of a highly electronegative nitrogen atom bonded to three hydrogen atoms. Hydrogen bonding is a stronger intermolecular force than dipole-dipole interaction.
Based on these considerations, ammonia (NH3) has a higher boiling point compared to sulfur hexachloride (SCl6). The stronger intermolecular forces, specifically hydrogen bonding in NH3, contribute to its higher boiling point.
However, to obtain the precise boiling point values, it is recommended to consult reliable reference sources or conduct empirical studies.
