ethyl ether
reason
vapor pressure is the pressure exerted by gas molecules at a
particular
temperature. The compounds having strong intermolecular
forces
will have tendency to remain is liquid state , since they
have
to overcome intermolecular forces to escape in to gaseous
state
So weaker the intermolecular force , higher will be the vapor
pressure
ethanol ,methanol, water have Hydrogen bonds hence have
strong intermolecular force and low V.P
Acetone has stronger dipole force than ether , due to this
V.P
of ether is highest
3. Considering intermolecular forces, which of the following liquids has the highest vapour pressure: acetone, methanol,...
3. Considering intermolecular forces, which of the following liquids has the highest vapour pressure: acetone, methanol, water, ethyl ether, or ethanol? Explain your reasoning.
For each of the following pairs of liquids, which species has the lower vapour pressure at room temperatures, and state the reason why (i.e. which is closer to its boiling point when at room temperature?): a. water (H2O) or methanol (CH3OH) b. 1-pentanol (CH3 (CH2 )4OH) or 1-hexanol (CH3 (CH2 )5OH) c. methylchloride (CH3Cl) or chloroform (CHCl3 ) I got the answers for most but I do not know how to compare them when they have similar intermolecular forces. For...
*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...

1. Indicate which is the strongest intermolecular force between each of the two molecules below: a. H2S and H2O b. C4H10 (butane) and (CH3)2CO (acetone) 2. Considering properties of liquids: a. Surface tension is proportional to the magnitude of intermolecular forces and/or attractive forces among the molecules in the liquid. With this perspective in mind, which in the following pair of liquids would have the highest surface tension: H2O or CHCl3 (chloroform) b....

Common Polar Solvents Common Nonpolar Solvents Water (H2 O) Hexane (C6H14) Acetone (CH3COCH3) Diethyl ether (CH3CH2OCH2CH3) Methanol (CH3OH) Toluene (C7H8) Ethanol (CH3CH2OH) Carbon tetrachloride (CCl4)
INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
