To solve a system of equations by addition or subtraction (or elimination)‚ you must eliminate one of the variables so that you could solve for one of the variables. First‚ in this equation‚ you must look for a way to eliminate a variable (line the equations up vertically and look to see if there are any numbers that are equal to each other). If there is lets say a –2y on the top equation and a –2y on the bottom equation you could subtract them and they would eliminate themselves by equaling zero

This reactivity makes alkyl halides useful chemical reagents. Nomenclature According to IUPAC‚ alkyl halides are treated as alkanes with a halogen substituent. The halogen prefixes are Fluoro-‚ Chloro-‚ Bromo- and Iodo-. Examples: H Cl

Alkenes by Elimination Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 11/12/03 Abstract: The objective of this experiment is to successfully perform a dehydration of a 2-butanol and a dehydrohalogenation of 2-bromobutane to form the products 1-butene‚ trans-2-butene‚ and cis-2-butene. It was found that a dehydration of 2-butanol yielded 4.6% 1-butene‚ 67.3% trans-2-butene‚ and 28.1% cis-2-butene‚ and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene‚ 69.9% trans-2-butene

Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)

Title: Competing Nucleophiles (Exp 24‚ pp 211-221‚ pp 808-823‚ pp 836-842) Purpose: The purpose of this experiment is to determine the nucleophilic strength of chloride and bromide ions as it reacts with 1-butanol (n-butyl) and 2-methyl-2-propanol (t-butyl alcohol) under SN1 and SN2 conditions. Method: 40 g of ice and approximately 30 ml of sulfuric acid is cautiously added to a 100 mL beaker respectively. Weigh 7.6 g of ammonium chloride and 14.0 g of ammonium bromide and place it in

Gauss-Jordan Matrix Elimination -This method can be used to solve systems of linear equations involving two or more variables. However‚ the system must be changed to an augmented matrix. -This method can also be used to find the inverse of a 2x2 matrix or larger matrices‚ 3x3‚ 4x4 etc. Note: The matrix must be a square matrix in order to find its inverse. An Augmented Matrix is used to solve a system of linear equations. a1 x + b1 y + c1 z = d1 a 2 x + b2 y + c 2 z = d 2 a3 x + b3 y + c3 z = d 3
