which has lowest boiling point

Which molecule will have the lowest boiling point?

One made of polar molecules Answer : The correct answer is : The molecular solids would have the lowest boiling point because of WEAK INTERMOLECULAR FORCES. These are solids , which are made up of molecules and sometimes atoms ( Noble gases , since they are inert ) . Hence the unit of molecular solid is a molecule .

Which one has a higher boiling point?

WATER has the highest boiling point because water is a strong dipole and the molecules are interconnected by hydrogen bonds. PH3 = polar molecule = Dipole-Dipole Forces. H2S = polar molecule = Dipole-Dipole Forces.

What liquid has a low boiling point?

Liquid helium has the lowest boiling point of all — about -452 degrees Fahrenheit, only 4.2 ...

Which one has the highes boiling point?

Which one has higher boiling point aldehyde or ketone? 1 Expert Answer. Ketones have a higher boiling point than aldehydes. The reason for this is because the carbonyl group of a ketone is more polarized than that of an aldehyde. Put differently, the oxygen of the ketone carbonyl has a greater partial negative than the oxygen of the aldehyde ...

Which has the lowest boiling point NH3 PH3 AsH3 SbH3?

Hence correct order of boiling point is: H2O > SbH3 > NH3 > AsH3 > PH3.

Which liquid has lowest boiling point?

Liquid helium has the lowest boiling point of all — about -452 degrees Fahrenheit, only 4.2 degrees Celsius above absolute zero.

Which one has lowest boiling point Mcq?

Thus, 2-Methylpropane has the lowest boiling point among the given options.

Which of the following has lowest boiling point CH4 h2o HF C2H5OH?

CH4 is the correct answer. Methane has the low boiling point cause it have very weak intermolecular force of attraction.

Why liquid has low boiling point?

The higher the vapor pressure of a liquid at a given temperature, the higher the volatility and the lower the normal boiling point of the liquid. Hence liquids with lower boiling point are more volatile.

What liquid has the highest boiling point?

CH3COOH has the highest boiling point because it has hydrogen bonds. These are the strongest intermolecular forces hence making it to have the highest boiling point.

Which has the lowest boiling point quizlet?

The only intermolecular force present is a relatively weak dispersion force (small molar mass). CO2 will have the lowest boiling point.

What has the lowest melting point?

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