MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...

PREPARATION OF PHARMACEUTICALS - Fischer Esterification
Reactions
Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...

What are the desirable characteristics of a solvent to be used
in the recrystallisation of a solid product? (Hint: what is the
underlying purpose of doing recrystallisation, aside from making
the product look attractive?)
EXPERIMENT5 PREPARATION OF BENZOIC ACID Oxidation of a Primary Alcohol In this experiment, a primary alcohol (benzyl alcohol) is oxidised to a carboxylic acid (benzoic acid) by a strong oxidising agent (potassium permanganate) Because the synthesis reaction is carried out in basic conditions, the carboxylic acid...

you!
Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
