To confirm‚ a successful reaction‚ AgNO3 was added to the 2-chloro-2-methylbutane. A white precipitate formation confirmed a successful Sn1 reaction. Introduction Nucleophilic substitution reactions such as Sn1 and Sn2 allow us to convert one functional group to another. For Sn1 reactions‚ a tertiary alcohol‚ such as 2-methyl-2-butanol is most favorable for the reaction because when the leaving group leaves‚ it will leave a + charge on the carbon it was attached to‚ and a tertiary carbocation is

compounds were determined by the use of litmus paper. Ignition test was conducted using 3 to 5 drops of the sample in a small evaporating dish and light with a match. Lastly‚ the infrared spectrum was use to classify organic compounds according to their functional groups. INTRODUCTION Organic compounds are the complex compounds of carbon. Because carbon atoms bond to one another easily‚ the basis of most organic compounds is comprised of carbon chains that vary in length and shape. Carbon atoms have

with itself and hydrogen to form both chains and rings called hydrocarbons. Because the covalent bond between carbon and hydrogen is nonpolar‚ these carbon skeletons are hydrophobic. Functional groups can be added to carbon skeletons to make them more hydrophilic. Differences in the carbon skeleton and attached functional groups cause organic molecules to have different chemical properties. The chemical properties of a molecule determine how it interacts with other molecules and the

Functional groups are usually atomic groups that occur naturally within the organic molecule. They convene chemical properties to the perspective particle. Each organic molecule type hold a specific type of functional group. Functional groups in different biological molecules play a significant role in the bio-molecules formation such as protein‚ DNA‚ sugars‚ amino acids‚ lipids and carbohydrates. Functional groups include the carbonyl‚ methyl‚ hydroxyl‚ amino‚ phosphate‚ and sulfhydryl. These are
