  • Online Middle School Chemistry Resource

    Updated: 2012-08-31 20:25:04
    The ACS Education Division has developed a new middle school chemistry resource, "Middle School Chemistry: Big Ideas about the Very Small." This free, six-chapter resource can serve as either a stand-alone chemistry unit or as a supplement to any middle school science curriculum. "Middle School Chemistry" uses a hands-on inquiry approach along with specially designed molecular model animations, to take students from concrete experiences to an understanding of the world of atoms and molecules. Share this free resource with middle school teachers you know.

  • Re: Freezing Behaviour of 36% Hydrochloric Acid

    Updated: 2012-08-31 20:22:22
    Couldn't you test by, say, cooling a small graduated vial (careful about shattering!) with 35% acid in a cooling bath? -40 C shouldn't be very hard to reach using say CaCl2 + Ice or Octane + Dry Ice.

  • Re: Possible products in this reaction?

    Probably a silly question; but how come H2SO4 doesn't dehydrate it to form a diene or hydrate it to form a diol?

  • Aldol Condensation and Steric Shielding (Solvent Selection Guidelines)

    Updated: 2012-08-31 19:57:10
    The Wikipedia article on Aldol Condensation says at one point:The reaction between menthone and anisaldehyde is complicated due to steric shielding of the ketone group. The solution is use of a strong base such as potassium hydroxide and a very polar solvent such as DMSO in the reaction belowWhy does a polar solvent help against steric shielding? More in general, how does one go about selecting a solvent for aldol condensation; any guidelines? Especially curious to know if solvent selection could be made to reduce undesirable self condensation?

Imagine if Agatha Christie had to write that every time she had to mention the poison used in the murder, or if Hitchcock’s leading man had to vocalise it in the courtroom. Well they’d never get the book or the film down to a manageable size. It’s much easier to say strychnine From the [...]
