Homework Answers
5. You have to cool the product In order to precipitate as much as possible and increase % yield. You need to rinse it in cool water to avoid losses by solubility of the compound.
6. As you increase the carbocation character, you could favor the formation of an alkane by elimination reaction.
7. You will obtain a low o nule yield of product due to high steric hindrance of the nucleofile.

NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In...

I need help with the writing a paragraph of ``OBSERVATIONS`` part of the Lab report. It is a substituition and Elimination exp. Please see exp.details below: We started with 2.1 g of solid. Final mass after crystalization was 1.1g. Melting point of the product was 36.4 C. Therefore 2-napthyethyl ether formed based on BP. The product formed colorless crystalline solid. Procdure: a solution of 1g of 2-naphtol was mixed with 4.0mL of 30% aqeous potassium hydroxide and 25 mL of...
