Water had the strongest intermolecular forces and evaporated most slowly. The strength of the intermolecular forces in isopropyl alcohol are in between water and acetone, but probably closer to acetone because the water took much longer to evaporate.
Which liquid has the strongest intermolecular forces water or ethanol?
Water has strong intermolecular forces (hydrogen bonds). Ethanol (CH3CH2OH) and methylated spirits (mainly ethanol (CH3CH2OH) with some methanol (CH3OH)) both have hydrogen bonds but these are slightly weaker than the hydrogen bonds in water.
Why is water the strongest intermolecular force?
A property of water is that it has strong intermolecular forces as a result of hydrogen bonding and the dipole moments created by the strong electronegative oxygen and the hydrogen. … The energy required to break these bonds accounts for the relatively high melting point of water.
Does water have stronger intermolecular forces?
Water has very strong intermolecular forces, hence the low vapor pressure, but it’s even lower compared to larger molecules with low vapor pressures. Viscosity is the property of fluid having high resistance to flow.
What is the strongest intermolecular forces in alcohols?
Alcohols contain the hydroxyl group (O—H) which produce intermolecular forces of attraction through hydrogen bonding. Hydrogen bonds are much stronger than Van Der Waals’ intermolecular forces.
What are the intermolecular forces between water and ethanol?
In both pure water and pure ethanol the main intermolecular attractions are hydrogen bonds. In order to mix the two, the hydrogen bonds between water molecules and the hydrogen bonds between ethanol molecules must be broken. Energy is required for both of these processes.
What intermolecular forces does water have?
Water molecules are held together by hydrogen bonds. Hydrogen bonds are a much stronger type of intermolecular force than those found in many other substances, and this affects the properties of water.
Why does water have stronger intermolecular forces than isopropyl alcohol?
Isopropyl alcohol is a polar covalent molecule with hydrogen bonding as the predominant intermolecular force. Since the melting and boiling point of isopropyl alcohol is lower than that of water, the hydrogen bonding in it is weaker than that in water.
Is water stronger than alcohol?
Water has greater degrees of hydrogen-bonding in the bulk liquid. … As a result, it is more difficult to deform the surface of water than the surface of ethyl alcohol. Therefore, since water molecules on a liquid surface are harder to push down on the surface tension is higher for water than for ethyl alcohol.
What intermolecular forces are present in alcohol?
There are basically 3 – dipole/dipole, London Dispersion, and H-Bonds. The length of the alcohol basically determines whether or not they associate with water.
Does ethanol have higher IMF than water?
Water has strong intermolecular forces (hydrogen bonds). Ethanol (CH3CH2OH) and methylated spirits (mainly ethanol (CH3CH2OH) with some methanol (CH3OH)) both have hydrogen bonds but these are slightly weaker than the hydrogen bonds.
Which of the following will have the strongest intermolecular forces?
Dipole-dipole interactions are the strongest intermolecular force of attraction.
