Question

What intermolecular forces are present in each of the substances? CH4,C3H8,CH3F,HF, C6H5OH (dispersion forces, dipole-dipole forces, or hydrogen bonding);A sample of ideal gas at room temperature occupies a volume of 34.0L at a pressure of 782torr . If the pressure changes to 3910torr , with no change in the temperature or moles of gas, what is the new volume, V2; and If the volume of the original sample in Part A (P1 = 782torr , V1 = 34.0L ) changes to 65.0L , without a change in the temperature or moles of gas molecules, what is the new pressure, P2. A sample of gas in a balloon has an initial temperature of 9?C and a volume of 1200L . If the temperature changes to 85?C , and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas? What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 9?C , V1= 1200L ) to a volume of 2400L ? Assume no change in pressure or the amount of gas in the balloon. Oxygen used in respiratory therapy is stored at room temperature under a pressure of 150 atm in a gas cylinder with a volume of 60.0 L.What volume would the oxygen occupy at 0.730atm ? Assume no temperature change; and if the oxygen flow to the patient is adjusted to 6.00L/min at room temperature and 0.730atm , how long will the tank of gas last?

Explanation / Answer

CH4- As the molecule is non- polar and no electronegative atom is present to which hydrogen bonds can be associated, only DISPERSION forces are present.

C3H8- As the molecule is non- polar and no electronegative atom is present to which hydrogen bonds can be associated, only DISPERSION forces are present.

CH3F- This molecule is polar, so it has dipole-dipole interactions. Although electronegative atom F is present, but there not a H donor to which hydrogen bonds can be associated, So, in this molecule DISPERSION and DIPOLE-DIPOLE forces are present.

HF- This molecule is polar, so it has dipole-dipole interactions. It has electronegative atom F is present and H to which hydrogen bonds can be associated, So, in this molecule DISPERSION, DIPOLE-DIPOLE and HYDROGEN BONDING are present.

C6H5OH-This molecule is polar, so it has dipole-dipole interactions. It has electronegative atom O is present and H to which hydrogen bonds can be associated, So, in this molecule DISPERSION, DIPOLE-DIPOLE and HYDROGEN BONDING are present.
