Although ethanol has a higher molar mass than water and exhibits the same IMF as water, ethanol shows a much larger drop in temperature during evaporation. Why is that: Be specific.

What kind of intermolecular forces act between a carbon monoxide molecule and a formaldehyde (H₂CO) molecule? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

Compare the boiling points of the various isomeric hydrocarbons shown in the table below. Notice the relationship between boiling point and structure; branched-chain hydrocarbons have lower boiling points than the unbranched isomer. Speculate on possible reasons for this trend. Why might the intermolecular forces be slightly different in these compounds? Compound Boiling Point (°C) 68.9 Hexane 3-Methylpentane 2-Methylpentane 2,3- Dimethylbutane 2,2- Dimethylbutane 63.2 60.3 58.0 49.7 The more branched structure has smaller exposed surface and hence weaker dispersion intermolecular forces. The more branched structure has larger exposed surface and hence weaker dispersion intermolecular forces. The more branched structure has larger exposed surface and hence stronger dispersion intermolecular forces. The more branched structure has smaller exposed surface and hence stronger dispersion intermolecular forces.

The normal boiling point of toluene (C7H8) is 111°C and its enthalpy of vaporization is 30.8 kJ/mol. a) Calculate the vapor pressure of toluene at 55°C, in mmHg.   b) If another compound, A, has a vapor pressure of 650 mmHg at 120°C, which of the two compounds, A or toluene, is more volatile? Explain your answer.

What kind of intermolecular forces act between a chloromethane (CH3C1) molecule and a hydrogen sulfide molecule? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

The structural formula of glucose is given. Identify the strongest intermolecular force present in glucose.

Please don't provide handwritten solution ....

Give a clear explanation answer

I'm lost on where to start with this question

Which do you expect to have the greatest surface tension? ethanol CH3CH2OH, ethane CH3CH3, chloroethane CH3CHCI, bromoethane CH3CH2Br
