Place the following compounds in order of Increasing vapor pressure. H.C. C H₂ OHHC-C H₂ ethanol Lowest Vapor Pressue 0 0 Highest Vapor Pressure pentane CH3 H3C. H3C-CH3 ethanal ethane

How do I approach this question

Order it! Lowest to Highest!! Based on intermolecular forces, predict the ordering from LOWEST boiling point to HIGHEST boiling point.     CH3CH2CH2OH  Ne  CH3COCH3 CH4 CH3CH2CH3

The predominant intermolecular force between molecules of the following compound is: H H-c-OH H-C-cH H. H.

Give detailed Solution with explanation needed..don't give Handwritten answer...

Based solely on IMF, list the following substances from highest vapor pressure to lowest vapor pressure: CH3CH2OH , CH3CH2Br , CH3CH3 and BaCl2

(e) lowest boiling point CH3CHCHCH3 OCH3CH₂CH3 OCH₂CH₂ Since this molecule is ---Select--- (f) highest boiling point HCI HBr HF Since this compound has ---Select--- (g) lowest vapor pressure at 25°C OCH3CH₂OCH₂CH3 CH3CH₂CH₂CH₂OH OCH3CH₂CH₂CH3 Since this compound has ---Select--- and ---Select--- ♥ than the other two, it has the ---Select--- ↑ ---Select--- unlike the other two compounds, it has the ---Select--- unlike the other two compounds, it has the ---Select--- and will have the lowest boiling point. intermolecular forces and will have the highest boiling point. intermolecular forces and will have the lowest vapor pressure.
