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

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.
CH3OH has the highest boiling point of the three.
Acetone ( CH3OCH3) has a higher boiling point than propane ( CH3CH2CH3 )
Both are nonpolar compounds, so the difference in molar mass (more than 30% heavier) is determining the difference in boiling points.
This is carbon tetrachloride with the boiling point +76,72 oC.
CH3Br has a higher boiling point.
CH4
Ch3ch3
C2h6
Which one has higher boiling point ch4 and C2H6
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
The boiling point of water will be greatest at that point on Earth that is the closest to sea level. Boiling point of water depends on the atmospheric pressure. The boiling point of water varies depending on the weather. At low atmospheric temperatures due to weather or due to being up a mountain, the water will boil below its "normal" boiling point of 100 oC
These boiling points are:* CF4: -127,8 0C* CHF3: -82,1 0C
At sea level the boiling temperature of water is 212o Fahrenheit. At different air pressures the boiling temperature changes. Higher air pressures require higher temperatures to boil. For example, if you go to a mountain top you could lower air pressure until water could boil at say 99o Fahrenheit. If you change substances, from water to something else, that substance would have its own individual boiling temperature, the point at which it changes from liquid to gas.
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
K2S will have high boiling point than CH3Cl.
CH3NH2 has the higher boiling point as it has a hydrogen bond between the molecule which is a stronger intermolecular attractive force, whereas CH3CH3 only has covalent bonds which are weaker intermolecular attractive forces.
Chlorine has higher boiling point.
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
The boiling point is higher.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
The boiling point is always higher than the melting point.
iodine is having higher boiling point
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Higher then the boiling point of the solvent.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
