(b) Boiling point of HF is highest due to the H-bonding. For other halogen acids boiling point increase in the order HCl
Which of the following hydrides is most volatile?
These are the hydrides of group 16 and we know that the electronegativity decreases down the group. As down the group the atom size increases so the Vander waals force of attraction increases so the volatility decreases. The last element is Te in group 16. So the most volatile is $${{text{H}}_{text{2}}}{text{Te}}$$.
What is the least volatile hydrogen halide?
HBr. HF is least volatile due to presence of intermolecular hydrogen bonding in the molecules.
Is HF most volatile?
HF is least volatile whereas HCl is most volatile.
Which of the following is most volatile?
From the above discussion, it is clear that the boiling point and stability of ${text{HCl}}$molecule is lower than the others, so ${text{HCl}}$ is the most volatile compound. So, the correct answer is “Option B”.
Which of the following is most volatile ch3ch2ch2nh2?
Hence CH3CH2CH3 will the most volatile of them all.
Which of the group 16 element is most volatile?
Explanation:Hydrides of group-16 elements show volatility in the order : H2S > H2Se > H2Te > H2O Oxygen is most electronegative than other elements of group-16 it undergoes hydrogen bonding. Due to strong intermolecular hydrogen bonding in H2O it shows lowest volatility.
Is h20 least volatile?
Volatility is inversely proportional to boiling point. Order of volatility H2Te > H2Se > H2S > H2O Water has the highest boiling point and thus is least volatile.
Is h2so4 volatile?
We know that one of the many properties of sulphuric acid is that it is a non- volatile acid. Sulphuric acid has high boiling points and this is why it is used in the preparation of volatile acids such as Hydrochloric acid i.e. HCl, HNO3 and acetic acid from their salts.
How do you know which molecule is more volatile?
Volatility is indicated by a substance’s vapor pressure. It is a tendency of a substance to vaporize or the speed at which it vaporizes. Substances with higher vapor pressure will vaporize more readily at a given temperature than substances with lower vapor pressure.
What is the order of stability of hydrogen halides?
HF>HI>HBr>HCl.
Which is more volatile HF or h20?
This is due to the fact that the bonding between the molecules is weak in volatile compounds and less energy/heat is required for the liquid to boil. … H2S is most volatile(least boiling point) as it is does not have any hydrogen bonding like HF and H2O.
Which is more volatile Hi or h2 S o4?
Reason: HI is more volatile than H2SO4 29.
Is hno3 volatile?
Nitric acid is a more volatile acid than sulphuric acid is displaced by sulphuric acid from metal nitrates.
Which hydride is least volatile?
Water (H2O) is least volatile due to the association of H2O molecules through hydrogen bonding. However hydrogen bonding is not present in other hydrides.
What is the correct order of volatility?
Volatility is governed by the intermolecular forces of a compound. Molecular weight increases with increase in the Van der Waal forces. So, the predictable order has to be: .
How does acid strength of hydrides of group 16 vary down the group?
The p-Block Elements. Arrange hydrides of group 16 in order of increasing acidic strength. Electron density on central atom decreases and consequently its tendency to donate a pair of electron decreases and hence its Acid strength increase. H2O < H2S < H2Se < H2Te.
Which of the following is most volatile o-nitrophenol?
The structure of para-nitrophenol is: Hence, we can say that o-nitrophenol is more volatile than p-nitrophenol because of intermolecular hydrogen bonding in p-nitrophenol.
Which amines are volatile?
Ammonia is highly volatile, whereas amines such as 2-amino-2-methyl-propanol (AMP) and monoethanolamine (MEA) are also volatile, although less than ammonia.
Which of the following is most volatile p nitrophenol?
o-nitrophenol is more volatile than p-itrophenol due to presence of intramolecular hydrogen bonding. In para nitrophenol intermolecular hydrogen bonding is present.
Which among the following is most volatile metal?
Next to mercury, the most volatile metals are the heavier alkali metals. Whereas mercury has a vapour pressure of 1 Pa at 42 °C, cesium has a vapor pressure of 1 Pa at 144 °C.
Which of the following is more volatile Mcq?
Which of the following is more volatile? Explanation: DRAM is said to be more volatile because it has a capacitor as its storage element in which the data disappears when the capacitor loses its charge so even when the device is powered the data can be lost. 6.
Which of the following is most volatile ch4 sih4 geh4 snh4?
wt. The more is the volatile character.
