are divided into three classes: alkanes have only single bonds‚ and are said to be saturated; alkenes and alkynes have carbon-carbon double or triple bonds‚ and are said to be unsaturated. Aromatic hydrocarbons are cyclic compounds whose structure is related to that of benzene‚ with six -electrons in a six-member ring. Aliphatic Hydrocarbons such as Alkanes are relatively inert to chemical oxidizing agents such as neutral or alkaline permanganate‚ where alkenes are readily oxidized at room temperature

unknown gives a positive result in nitration test and gives no brown precipitate in oxidation test. The unknown is an aromatic and non-alkylated compound. _______________________________________________ Introduction: Hydrocarbons are organic compounds that composed of only hydrogen and carbon. There are two major types of hydrocarbons; aliphatic (saturated and unsaturated) and aromatics. Aliphatic compounds are characterized by a continuous or branched chain arrangement aliphatic compounds are

as follows: Nitration test (negative)‚ Bromine test (positive) and Basic Oxidation test (positive). From these results the unknown sample can be classified as non-aromatic and unsaturated. INTRODUCTION Hydrocarbons are organic compounds that consist of only C and H atoms. They include the alkanes‚ alkenes‚ alkynes‚ and aromatic hydrocarbons. Because of their relatively non-polarity‚ all hydrocarbons are insoluble in water. When hydrocarbons burn in sufficient oxygen‚ carbon dioxide and water

Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

etc) 2) work in a short amount of time (instantly to 5 minutes) 3) only work with one functional group The following are chemical tests that we will use in this class. Some cover two related functional groups (such as the bromine test for alkenes and alkynes)‚ while other only a specific subcategory of that functional group (such as the iodoform test for methyl ketones). In some cases there can be false positives (compounds which do not have the functional group still give a result test) or false

aliphatic hydrocarbons: o Alkanes ▪ A hydrocarbon with only single bonds between carbon atoms. ▪ General formula is Cn H2n+2 ▪ All alkanes have the ending –“ane” ▪ Any alkyl branches in the carbon chain have the suffix –“yl” ▪ The name of a branched alkane must indicate the point of attachment of the branch. o Alkenes ▪ A hydrocarbon that contains at least one carbon – carbon double bond. ▪ General formula is Cn H2n o Alkynes ▪ A hydrocarbon that
