Which has a higher boiling point Kr or Xe?
These intermolecular forces are dominant in nonpolar substances and the strength is highly dependent on the molecular weight. Since Xe is heavier than Kr, it will have stronger London-dispersion forces and will be more difficult to boil–Xe will have a higher boiling point.
Which of the following has the highest boiling point RN Xe Kr?
Among the noble gases, Xe has the highest boiling point. The boiling points (in K) of He, Ne, Ar, Kr, Xe and Rn are 4.0, 27.0, 87.0, 121, 165.0 and 211 respectively.
Does KR have a higher boiling point than he?
Because of larger size the outer electrons are less tightly held in the larger atoms so that instantaneous dipoles are more easily induced resulting in greater interaction between argon atoms. Therefore, its boiling point (-108.1 °C) is more than that of Helium….Which element has the highest boiling point? A. He. B. Ne. C. Kr. D. Xe.
| Element | Atomic Number |
|---|---|
| Krypton | 36 |
| Xenon | 54 |
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 …
Which of the following has highest boiling point I KR II Xe III He iv ne?
Among the given noble gases Xenon has the highest boiling point.
What is the boiling point of Xe?
-162.6°F (-108.1°C)
Xenon/Boiling point
Which one of the following hydrocarbons would have the highest boiling point?
heptane
Hydrocarbon boiling point is also dependent on the length of the carbon chain, and increases as the length of the chain increases. We can conclude that heptane likely has the highest boiling point of the answer choices, as it does not branch and has the longest carbon chain.
Why does Xe have a high boiling point?
In your case, xenon has a much bigger electron cloud than neon. Moreover, xenon’s outermost electrons are further away from the nucles, which implies that they are not held as tightly as neon’s electrons. Therefore, xenon’s boiling point will be higher than neon’s.
Which hydrocarbon has highest boiling point?
Dodecane is a liquid alkane hydrocarbon with a boiling point between 214 0C to 218 0C. The chemical formula for dodecane is CH3(CH2)10CH3.
Which one of the following aqueous solutions has the highest boiling point?
Answer: (b) As we know greater the value of van’t Hoff factor higher will be the elevation in boiling point and hence higher will be the boiling point of solution. Hence, 1.0 M Na2St4 has highest value of boiling point.
Which of the following has highest boiling point NE He ch4 XE?
Among the given noble gases Xenon has the highest boiling point. These elements belong to group 18 of the periodic table thus they are more stable…
Does CO2 or CS2 have a higher boiling point?
CS2 has a higher boiling point than CO2 despite having similar intermolecular forces because it has a larger molar mass. Until a certain point, the potential energy of molecules decrease as they get closer to one another.
