Categorise this alkyl halide as primary / secondary / tertiary, and identify the most electrophilic (8+) location within the molecule. a Br е Select one: Secondary alkyl halide; the electrophilic location is b Secondary alkyl halide; the electrophilic location is a Tertiary alkyl halide; the electrophilic location is a Primary alkyl halide; the electrophilic location is a 0 Tertiary alkyl halide; the electrophilic location is e
HO Regarding the following reaction: 1) a. Classify the alkyl halide as tertiary, secondary, or primary. b. Based on your answers to la, deduce whether the alkyl halide would be suitable for (i) only S2 reactions, (ii) only Ss 1 reactions, or (1) both/either S2 or S1 reactions. 2) a. Classify the nucleophile (the electron-sharer) as either strong or weak b. Based on your answer to 2a, deduce whether the nucleophile would be suitable for (i) only Sw2 reactions, (1)...
why must synthesized crude tertiary alkyl halide be dried carefully with calcium chloride before the distillation for purifying purpose? (try to answer what kind of reaction could be happening with water and alkyl halide?)
Match the following statements with reaction mechanism
SN1, SN2, E1, or E2. A statement may be true
for one or more mechanisms.
a. The mechanism involves carbocation intermediates. b. The mechanism has two steps. c. The reaction rate increases with better leaving groups. d. The reaction rate increases when the solvent is changed from CH3OH to (CH3)2SO e. The reaction rate depends on the concentration of only the alkyl halide. f. The mechanism is concerted. g. The reaction of CH3CH2Br...
Draw the structural formula for a compound that contains a tertiary alcohol, a secondary alkyl halide, and primary, secondary and tertiary hydrogens. a. Indicate the number of beta-hydrogens relative the alkyl halide. b. Name the compound you just drew.

Experiment 4: Synthesis of a tertiary alkyl halide Page 5 of 6 Assuming that all other experimental conditions are the same; explain if an S,1 reaction would still occur if the following changes were made. If an Sk1 reaction would still occur: then state the IUPAC name and draw the structure of the product formed compare the rate of reaction to the rate of the original reaction (in...
Experiment 4: Synthesis of a tertiary alkyl halide Page 3 of 6 Distillation is a technique that is to purify liquid compounds. Use theoretical data to explain how distillation is used to separate the target product in this reaction from any residual unreacted starting material in the reaction. [2 marks]
Tertiary alcohols undergo elimination via an E1 mechanism since the tertiary carbocation intermediate is especially stable. Zaitsev's rule is followed in the elimination to give the more substituted alkene as the major product Draw curved arrows to show the movement of elections in this step of the mechanism
When determining which mechanism (E1 or E2) occurs, the following process is helpful: 1) Determine the substitution (methyl, 1º, 2º, or 3“) of the alkyl halide 2) Determine the strength of the nucleophile Please fill out the following table, indicating the category of reaction (E1 or E2) that will occur in each set of alkyl halides and nucleophiles. If no reaction occurs, write 'NR: Alkyl Halide Strong Base Weak Base Methyl 1° 20 3° For each of the following reactions,...
