Look un n-butyl bromide. Assume that this alkyl halide was prepared instead of the chloride. Decide weather the alkyl halide would appear as the upper or the lower in the conical vial when washing with cold water. ( what is the density of the n-butyl bromide?)
Homework Answers
If anyone mix n-butyl bromide with cold water, n-butyl bromide would appear lower in the conical vial. This is because the density of n-butyl bromide is more than water (water density is 997 kg/m³ whereas n-butyl bromide density is 1.27 g/cm³) and hence it appear in the lower part.
More density compounds appear in lower part whereas the lighter compounds (with less density) appear upper level in the conical or separating vial.

If you prepared tert-butyl bromide by the procedure used for tert-butyl chloride, the product, and the aqueous solution would be so similar in density that you could not be sure which layer in the separatory funnel was a product to be retained, and which layer was aqueous acid to be discarded. How could you quickly decide whether the lower layer (first to be drawn off) should be discarded or saved?(It was a substitution experiment)

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...

monitor the completion of the reaction and a salt, silver nitrate,

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...

BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...
