with its liquid. A solid compound changes to a liquid when the molecules acquire enough energy to overcome intermolecular forces holding them together in an crystalline lattice structure. The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally through multiple trials for an unknown and referenced against the chemistry literature for a known

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

Synthesis of Phenacetin from para-Acetamidophenol Aims: To determine how phenacetin from acetamidophenol (known as paracetamol) is synthesized using Sodium Ethoxide Iodine‚ which is the Williamson Ether synthesis. Experimental: Sodium metal was patted dry to remove any oil and was cat into small pieces. A dry 100cm3 round bottom flask was placed on a cork ring‚ on a balance and tarred sodium metal (0.6g) was placed into the flask. The flask was then attached to the dry reflux condenser

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

Synthesis of Salicylic Acid from Wintergreen Oil Objective – Preparation of salicylic acid (organic synthesis) from methyl salicylate utilizing previously used procedure from the nineteenth century. The final product will then be evaluated in comparison to salicylic acid made from benzene. Discussion – In this synthesis‚ methyl salicylate is the starting material or precursor and salicylic acid is the target product. It is the major constituent of wintergreen oil. The difference in structures

II. Synthesis This activity helps me to understand myself better by knowing what people think of me. It aims to foster self-awareness and self-improvement. I found out that my family thinks that I am a responsible person in terms of sense of responsibility. But my brother thinks I’m immature. In terms of duties at home‚ my mother and father understand that I don’t perform my duties because I’m busy with my studies. My sister thinks it too but she justified that I perform when I’m not busy. When

Synthesis of 1-Bromobutane from 1-Butanol Reference: Discovering Organic Chemistry in the Laboratory; John R. Ganson Ph. D‚ Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol‚ to a better leaving group. In order for this reaction to synthesis 1-Bromobutane

Synthesis The idea of gender wage discrimination being widely practiced in the United States today is a difficult concept for many to swallow. With the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964‚ the realization of the existence of the gender wage gap surprises many Americans. These authors bring to the forefront the idea that there is more to the gender wage gap then just companies discriminating against women and minorities. They sight many sources with defined data
