MgCl2 because it has more electrons (due to the Mg over Na). Because of the higher number of electrons, it has higher dispersion forces (attractive forces). This means that more energy (heat) is required to unstick the molecules into a different state of matter.
NaCl, due to complex arrangement and interaction of molecules, can't be easily explained by using simple dispersion, dipole-dipole interaction.
Although NaCl's higher melting point can be explained by its bonding in its crystal lattice arrangement compare to MgCl2.
Yes, chlorine has a higher boiling point than iodine. Chlorine has a boiling point of -34.6 degrees Celsius, while iodine has a boiling point of 184 degrees Celsius.
No, LiCl (Lithium chloride) will not have a higher boiling point than water. The boiling point of water is 100 degrees Celsius, whereas the boiling point of LiCl is significantly higher at 1382 degrees Celsius.
Pentanal has a higher boiling point than 3-methylbutanal because pentanal has a longer carbon chain, resulting in stronger van der Waals forces between its molecules. This leads to increased intermolecular interactions and hence a higher boiling point compared to the shorter 3-methylbutanal molecule.
Ethanol (C2H5OH) has a higher boiling point compared to methyl ether (CH3OCH3) due to hydrogen bonding in ethanol. Hydrogen bonding results in stronger intermolecular forces in ethanol, requiring more energy to overcome, hence a higher boiling point.
Heptane has 7 carbon atoms. So it has a greater surface area than methanol. Therefor heptane has a higher boiling point.In general, all else being equal the higher the molecular weight, the higher the boiling point. The molecular weight of methanol is 32, the molecular weight of heptane is 100. So, ignoring everything but that, you'd expect heptane to have a higher boiling point than methanol.A better question might be "why is the boiling point of methanol so much higher than that of ethane, which has a similar molecular weight (30)?" The answer to that is hydrogen bonding.
The magnesium chloride solution has a higher boiling point.
The lowest boiling point among CuCl2, HF, and MgCl2 is HF. This is because HF is a molecular compound with weaker intermolecular forces compared to the other two, which are ionic compounds with stronger electrostatic interactions between ions.
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.
Chlorine has a higher boiling point than oxygen. Chlorine's boiling point is -34.6 degrees Celsius, while oxygen's boiling point is -183 degrees Celsius.
In the same volume of water, one mole of MgCl2 will give rise to a greater boiling point elevation. This is explained by the fact that boiling point elevation is a colligative property, that is, the relative amounts of the constituents are important and not their identity. We can determine by inspection that, upon dissociation, more ions will be produced by MgCl2 than NaCl since there are more atoms in the MgCl2 molecule. So, for one mole of MgCl2, we will produce one mole of magnesium and two of chlorine (three total). For one mole of NaCl, we produce one mole each of potassium and chlorine. By employing the principle stated above, we can come to the correct conclusion.
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.
Yes, chlorine has a higher boiling point than iodine. Chlorine has a boiling point of -34.6 degrees Celsius, while iodine has a boiling point of 184 degrees Celsius.
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
The C7H16 isomer with the highest boiling point is heptane. This is because heptane has a linear structure with stronger London dispersion forces compared to its branched isomers, resulting in higher boiling points due to increased surface contact between molecules.
