Which of the following compounds will experience hydrogen bonding?
2 answers:
Answer:
HF will experience hydrogen bonding
Explanation:
Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).
Hydrogen bonding generally appears in covalent molecules.
Among all four given molecules, HF and are covalent molecules.
In HF, F is a highly electronegative atom attached to a H atom through a covalent bond. Therefore F atoms gets partial negative charge and H atoms gets partial positive charge.
Hence an interaction arises between H atom and F atom resulting formation of H-bonding.

Answer : The partial pressure of the in the tank in psia is, 32.6 psia.
Explanation :
As we are given 75 % and 25 %
in terms of volume.
First we have to calculate the moles of and
.
Now we have to calculate the mole fraction of .
Now we have to calculate the partial pressure of the gas.
conversion used : (1 Kpa = 0.145 psia)
Therefore, the partial pressure of the in the tank in psia is, 32.6 psia.
