Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

Compound 50‚ like its known analogue 3‚ involves an α‚β-unsaturated ketone‚ an acid-sensitive reactant‚ which prevents its direct synthesis in presence of protic solvents by refluxing. Despite of this characteristic‚ 50 was formed smoothly in 5 minutes by grinding chemistry‚ solely as E-isomer‚ without any evidence of decomposition after 1H and 13C MNR analysis. This synthetic approach provides easy access to such α‚β-unsaturated N-acylhydrazones‚ which are building blocks in the synthesis of nitrogen-containing

An analysis of Jonathan Kozol’s “The Human Cost of an Illiterate Society” In the story of “The Human Cost of an Illiterate Society” Jonathan Kozol reasons the negative effects of being illiterate. American illiterates are being shut down by society in a world where becoming a successful that seems uncertain for illiterates. Kozol shows to the reader the many risks that an illiterate American has to face on a daily basis and the dangers that results from it. “They cannot read traffic signs and‚

The objective of this experiment was to synthesize 3-nitrochalcone from 3- nitrobenzaldehyde. This was accomplished with a Diels-Alder reaction that utilized 3-nitrobenzaldehyde and acetophenone. After the reaction was completed‚ purification of the product was conducted using semi-microscale recrystallization. The melting point of the product was 136-141 oC‚ which is in the close vicinity of the literature melting point of 146 oC. The theoretical yield of 3-nitrochalcone was 0.253g and the

IMPORTANCE_OF_ADULT_EDUCATION">IMPORTANCE OF ADULT EDUCATION GOOD MORNING RESPECTED TEACHERS AND MY DEAR FRIENDS. EDUCATION IS THE MOST IMPORTANT THING WHICH IS MANDATORY FOR ALL THE PEOPLE LIVING IN THE WORLD. WITHOUT EDUCATION PEOPLE CAN BE EASILY CHEATED‚ BE-FOOLED & DECEIVED. THEY THEN ARE GIVEN THE NAME WHICH MOST PEOPLE DON’T LIKE IS THE WORD ’ILLITERATES’. THEY ARE DISCRIMINATED AND THEY CANNOT JOIN THE MAINSTREAM WHICH IS A DIFFICULT TASK. The scope of Adult education is very comprehensive
