What molecule has the highest freezing point?

(a) 1M glucose solution has highest freezing point because it has lowest ΔTf.

Which molecule has the highest boiling point?

Water in fact has the highest boiling point because although its individual hydrogen bonds are not as strong as hydrogen fluoride’s, the fact there are twice as many (two H instead of one) means the total strength of intermolecular forces between water molecules is greater than that of hydrogen fluoride, and so has the …

What does highest freezing point mean?

Molecules with stronger intermolecular forces are pulled together tightly to form a solid at higher temperatures, so their freezing point is higher. Molecules with lower intermolecular forces will not solidify until the temperature is lowered further.

Which has highest freezing point 4 points?

2)0.1M BaCl2 solution. 3)0.1M sugar solution. 4)0.1M FeCl3 solution.

Which molecule has the lowest boiling point?

The one with the weakest IMF will have the lowest boiling point. CH4 has only dispersion forces while all the others have dispersion PLUS either dipole-dipole (HCl, H2S, NH3), and/or hydrogen bonding (NH3). So, CH4 will have the lowest boiling point.

Which is the lowest boiling point?

Helium
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten. The unity used for the melting point is Celsius (C).

Which solutions have the highest boiling point?

0.1 M MgCl2. B.

0.1 M HClO4. C.

0.1 M KCl. D.

0.1 M KOH. E.

0.1 M LiNO3. Medium. Solution. Verified by Toppr. Correct option is A) 0.1 M MgCl2 solution has the highest boiling point. Elevation in the boiling point is a colligative property and depends on the number of solute particles.

Which solution has lowest freezing point?

1 M MgCl2. B.

1 M HClO4. C.

1 M NH4OH. D.

1 M KOH. E.

1 M LiNO3. Hard. Solution. Verified by Toppr. Correct option is A) All the given solutions have the same molarity. The solution which has the lowest freezing point temperature is 0. 1 M MgCl2.

Which of the following solution has highest freezing point?

1 molar of NaCl solution. B.

1 molar of KCl solution. C.

1 molar of CaCl2​ solution. D.

1 molar of urea solution. Medium. Solution.

1 molar of urea solution. 1 molar of urea solution has maximum freezing point.

Which one has the highest and lowest boiling point?

Helium has the lowest boiling point of all the elements at –452.074°F (–268.93°C) followed by hydrogen –423.16°F (–252.87°C). According to the CRC Handbook of Chemistry and Physics, the highest boiling point for an element is that of rhenium 10,104.8°F (5,596°C) followed by tungsten 10,031°F (5,555°C).

How do you find the substance with the highest freezing point?

Well, it’s a rather lengthy test, but one way to find the substance with the highest freezing point is to attempt to melt all the substances that you’re addressing. So, someone gives you a block of steel.

Which of the following compounds has the highest boiling point?

Compounds with stronger intermolecular forces have higher boiling points. CaCO3 — ion-ion attractions. CaCO3 is an ionic compound. It has the highest boiling points Next comes methanol, CH4O or CH3OH. Methanol has strong hydrogen bonds. It will have the next highest boiling point.

Why does liquid have a higher boiling point than gas?

Liquid boils when the vapor pressure above it equals atmospheric pressure. The key is to know which bonds require more energy for boiling to occur. If you are comparing molecules to determine which has the higher boiling point, consider the forces that are at work within the molecule.

What is the boiling point of water at 100 degrees Celsius?

The normal boiling point of water is 100 oC because this is the temperature at which the vapor pressure of water is 760 mmHg, or 1 atm.
