Both chloroform and carbon tetrachloride have the same tetrahedral molecular geometry - there are 4 atoms attached to a central carbon atom. In chloroform, there are 3 chlorine atoms and 1 hydrogen atom. In carbon tetrachloride, all 4 atoms surrounding the central carbon are chlorine atoms. So the difference between the two is simply replacing the 1 hydrogen atom with another chlorine atom. In essence, by doing this, the density of the compound is increased, due to the increase in mass (remember a chlorine atom has an Atomic Mass of 35 and hydrogen an atomic mass of 1). The density of chloroform goes from 1.48 g/mL to 1.58 g/mL when you replace chloroform's hydrogen with that chlorine atom. Since there is an increased mass in a given volume (1 mL), it takes just a little more energy (thermal) to get carbon tetrachloride atoms from the liquid state to the gas state, which is why CCl4 has a bp of around 76 (while chloroform's bp was around 62). -------------------------------------------------------------------------------------------------------------- Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the B.pt. Chloroform has mostly dispersion forces and very, very weak dipole-dipole. The reason Carbon tetrachloride has a higher boiling point is because the combined effect of all the dispersion forces are stronger than the intermolecular forces that exist in chloroform. Dispersion forces increase with increasing molecular weight and # of electrons.
What else can I help you with?
Why is the boiling point of carbon tetrachloride greater than silicontetrachloride?
tetrahedral molecules will have a better packing if the central atom is smaller than the peripheral ones. hence carbon tetrachloride has better packing and hence a higher boiling point. (this is most probably wrong, but seemed like a only explanation i could think of)
The normal boiling point of chloroform which has a higher vapor pressure than water at 100 degrees celsius is?
Chloroform has a normal boiling point of 61.2 degrees Celsius, which is lower than the boiling point of water. This means that chloroform will have a higher vapor pressure than water at 100 degrees Celsius, where water is at its boiling point but chloroform is not.
What is the normal boiling point of the chloroform which has a higher vapor pressure than water at 100 Celsius is?
The normal boiling point of chloroform is approximately 61.2°C. Since chloroform has a higher vapor pressure than water at 100°C, it means chloroform will boil first before water at that temperature, due to its lower boiling point.
Which would have a higher boiling point chloroform or bromoform?
Bromoform would have a higher boiling point than chloroform due to the presence of heavier bromine atoms. The increased molecular weight of bromoform leads to stronger van der Waals forces between molecules, resulting in a higher boiling point.
Is evaporation rate of iso propyl alcohol higher than chloroform?
Yes, the evaporation rate of isopropyl alcohol is higher than that of chloroform. Isopropyl alcohol evaporates more quickly due to its lower boiling point compared to chloroform.

The normal boiling point of chloroform which has a higher vapor pressure than water at 100 and degC is?
The boiling point of chloroform is 61,15 oC.

Why water is less volatile than carbon tetra chloride?
Water is less volatile than carbon tetrachloride because hydrogen bonding between water molecules leads to stronger intermolecular forces compared to the dispersion forces in carbon tetrachloride. This results in water having a higher boiling point and being less likely to evaporate easily at room temperature.
What is the evaporation rate of chloroform and water?
The evaporation rate of chloroform is higher than water due to its lower boiling point and higher vapor pressure. Chloroform evaporates quickly at room temperature, while water has a slower evaporation rate.
Is evaporation rate of iso propyl alcohol higher than chloroform?
Yes, the evaporation rate of isopropyl alcohol is higher than that of chloroform. Isopropyl alcohol evaporates more quickly due to its lower boiling point compared to chloroform.
Is chloroform less volatile than water?
Yes, chloroform is less volatile than water because it has a higher boiling point, meaning it evaporates more slowly at room temperature.
Will Carbon tetra chloride sink in sulfuric avid?
Yes, carbon tetrachloride (CCl4) will sink in sulfuric acid because it is denser than sulfuric acid. The density of carbon tetrachloride is higher than that of sulfuric acid, so it will sink to the bottom when the two substances are mixed.
Is chloroform more polar than ethyl acetate?
Yes, chloroform is more polar than ethyl acetate. Chloroform has a higher dipole moment due to the greater difference in electronegativity between the carbon and chlorine atoms, making it more polar than ethyl acetate.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
