• Write a suitable mechanism for the cleavage of butyl isopropyl ether with HI.

  In the attached document, this solution illustrates (1) the attack of the one molar equivalent of 1-propanol, (2) base takes off proton, carbonyl is reformed, kicking out the unprotonated carboxy acid group, (3) reforming the carboxy acid group, and (

• How would you synthesize propanoic acid from acetic acid?

  Make a grignard reagent out of the acetic acid by first reducing the carboxillic acid group to an alcohol by using LiAlH4 or NaBH4. Taking that alcohol and reacting it with HBr to make the halide.

• Drawing the Chemical Structure

  This gives a dicarboxylic acid - a feature of these systems is that, when heated, they undergo decarboxylation.

• Experimental analysis

  Not adding sulphuric acid would have made the reaction not feasible, since thre would be no collision between the reactant molecules. further more sulphuric acid remove water from the reaction of two molecules of alcohol to form ether.

• Solvent and Dielectric Constants

  Three common functional groups that can be ionized are the carboxylic acid group RCOOH (neutral) and RCOO- (ionized), alcohol rOH (neutral) and RO- (ionized), and amine RNH2 (neutral) and RHN- (ionized).

• Separation scheme for isolating benzoic acid

  Since benzoic acid is soluble in ether it will go in the ether layer and you will get two separate layers. The lower aqueous layer and the upper ether layer.

• Reaction Questions about Acyl Substitutions

  B is out, because this reaction will not occur if with a deprotonated carboxylic acid. This rules out D, too. 7) The product of the reaction is: a) an ether b) a lactam c) an anhydride d) a lactone D.

• Separating a Base, an Acid and a Neutral Compound

  This leaves an organic ether phase containing benzene and benzoic acid (phase 2).

• Write structures that all have the molecular formula C4H8O2
