Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how a

Examples of synthesis reactions: 1. Metal + oxygen → metal oxide EX. 2Mg(s) + O2(g) → 2MgO(s) 2. Nonmetal + oxygen → nonmetallic oxide EX. C(s) + O2(g) → CO2(g) 3. Metal oxide + water → metallic hydroxide EX. MgO(s) + H2O(l) → Mg(OH)2(s) 4. Nonmetallic oxide + water → acid EX. CO2(g) + H2O(l) → ; H2CO3(aq) 5. Metal + nonmetal → salt EX. 2 Na(s) + Cl2(g) → 2NaCl(s) 6. A few nonmetals combine with each other. EX. 2P(s) + 3Cl2(g) →

The purpose of this experiment was to perform a wittig reaction‚ the horner-emmons wittig specifically‚ reacting an aldehyde with an ylide to make an alkene. This particular variation of the wittig reaction has several advantages: It gives only the trans product; it uses a much milder base that is easier to handle; and it gives a water soluble byproduct which is easy to separate from the product. The reason that these advantages occur is a change in the structure of the ylide. Instead of a tripheylphosphine

However‚ Methanol could prove to be the solution the human race is looking for. Methanol could be used to replace gasoline in our cars for future years to come. Methanol is easy to make because it originates from our trash and biomass. That means that we won’t have to dig or frack for Methanol like we do for oil. When it comes to efficiency‚ Methanol shockingly wins that category over gasoline which is another advantage to converting to Methanol. On the other hand‚ Methanol has

Comment: Treat a Grignard reagent as an alkyl nucleophile i.e. CH3MgBr is equivalent to CH3- nucleophile. The Grignard reagent can also react with RX to form a longer chain alkane. Example: CH3CH2MgBr + CH3CH2Br CH3CH2CH2CH3 + MgBr2 In general‚ basicity parallels nucleophilic strength since both of them depend on the availability of the lone pair of electrons. The Grignard reagent is not only able to function as a nucleophile; it can operate as a base too by reacting with water to

How did you figure this out? The two unknown substances were the methanol and propenol because each of them were being tested in this experiment to discover the boiling point of each of these alcohols by analysing each of their temperatures to eventually discover the averages. 3.
