Presentation Transcript

  • Slides 2 through 5 were part of a series on H bonding.


Is acetone an h bond donor
Is acetone an H bond donor?

a. yes b. no c. can’t be determined


Is acetone an h bond acceptor
Is acetone an H bond acceptor?

a. yes b. no c. can’t be determined


Would there be h bonding in pure acetone
Would there be H bonding in pure acetone?

 a. yes b. no c. can’t be determined


Would there be h bonding in acetone that had water dissolved in it
Would there be H bonding in acetone that had water dissolved in it?

a. yes b. no c. can’t be determined


2-methylpropane and isopropyl alcohol have comparable molecular weights. Which substance will have stronger intermolecular interactions between its molecules?

a. 2-methylpropane b. isopropyl alcohol

c. ~same


What type of solvent would concentrated sulfuric acid be
What type of solvent would concentrated sulfuric acid be? molecular weights. Which substance will have stronger intermolecular interactions between its molecules?

  • Nonpolar

  • Hydroxylic

  • Polar Aprotic

  • None of the above


  • Slides molecular weights. Which substance will have stronger intermolecular interactions between its molecules?9 – 11 were part of a series covering H bonding and solubility. In slide 10, the pictures were not shown when the question was asked. A significant number of students answered yes. Then the pictures were shown the pictures and they were asked again.



Would cellulose be soluble in water
Would cellulose be soluble in water? water because they have many sites capable of H-bonding with water.

  • yes

  • no

  • can’t be determined


  • However water because they have many sites capable of H-bonding with water., cellulose has many OH groups that should readily H-bond with water, yet it doesn’t dissolve.

  • In this case, the intermolecular attraction through H-bonding between the cellulose chains due to the way they line up is so strong, that solvation does not occur easily


H bonding in amines
H-Bonding in Amines water because they have many sites capable of H-bonding with water.

Are 1 amines capable of H-bonding with themselves?

  • yes b. no

    c. impossible to determine


Amine structure
Amine Structure water because they have many sites capable of H-bonding with water.

Are 3 amines capable of H-bonding with themselves?

  • yes b. no

    c. impossible to determine


Physical properties
Physical Properties water because they have many sites capable of H-bonding with water.

If an amine is capable of H bonding does that increase or decrease its m.p. and b.p. relative to other compounds of similar polarity and m.w.?

  • increase b. decrease

    c. neither
