more electrons furthur down the group which means stronger van der waals forces exist so higher energy is needed to overcome these forces

What compound has -23 degrees Celsius melting point?
carbon tetrachloride (CCl4)
Why is the boiling point of NaCl higher than sucrose?
Nacl is a salt and forms ions in the solution Na+ Cl- , in other words it has 2 molecules dissociated. On the other hand Sucrose does not dissociate it stays as one mole of sugar. This is why the boiling point of Nacl is higher then Sucrose.
Can KCl and CCl4 form a solution?
KCl and CCl4 do they form solution
What is the formula for carbon tetrachloride?
Carbon tetrachloride has the chemical formula CCl4.
How many atoms of chlorine are in 2.00 moles of CCl4?
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
How much viscosity in cf4 ccl4 and cbr4?
CF4 has the lowest viscosity, followed by CCl4, and then CBr4. This is because viscosity is generally higher for heavier molecules due to stronger intermolecular forces that inhibit molecular motion.
Would H20 or CCl4 be expected to have a higher melting point?
H20 would be expected to have a higher melting point due to its stronger hydrogen bonding, compared to CCl4 which only has weak London dispersion forces.
Is CBr4 more volatile than CCl4?
ch4 is the most volatile
What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
Why is the boiling point of carbon tetrachloride greater than silicontetrachloride?
The boiling point of a compound is influenced by its molecular weight and intermolecular forces. Carbon tetrachloride (CCl4) has a higher boiling point than silicon tetrachloride (SiCl4) because carbon is more electronegative than silicon, leading to stronger dipole-dipole interactions in CCl4 compared to SiCl4, which only has weaker van der Waals forces between molecules.
What is the molar mass of adrenaline in a solution of 0.64 g of adrenaline in 36.0 g of CCl4 elevates the boiling point by 0.49?
First, calculate the molality of the adrenaline solution in CCl4 using the elevation in boiling point. Then, determine the moles of adrenaline in the solution using the molality and mass of CCl4. Finally, divide the mass of adrenaline by the moles to find the molar mass.
What is the equation of methane and bromine without the presence of sunlight?
The reaction is:3 CCl4 + 4 AlBr3 = 3 CBr4 + 4 AlCl3
What is the boiling point of C2H5Cl?

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.
When CCl4 boils what is inside the bubbles?
when any liquid BOILS the bubbles just contain the same substance, but just as a gas.now why did I put 'boils' in capitals?you know if you boil water there are tiny bubbles already forming before it is actually boiling. these are the gasses which were dissolved in the water.
Does H2O have a higher melting point than CCl4?
Yes. Water melts at 0 ºC. Tetrachloromethane (Carbon tetrachloride) has a melting point of -22 ºC
Why does H2O have a higher melting point than CCl4?
H2O has a higher melting point than CCl4 because it can form hydrogen bonds between its molecules, which are stronger than the dispersion forces in CCl4 molecules. The hydrogen bonds in H2O require more energy to break, resulting in a higher melting point compared to CCl4.
