    peak positions are singlet‚ doublet of triplets‚ doublet of triplets‚ singlet‚ and singlet‚ respectively. The two doublet of triplet peak sections at 6.7 ppm and 7.4 ppm represent the aromatic Hydrogens‚ which covers four of the nine Hydrogens proposed by the hypothesized formula. The integrated values for the aromatic peaks includes 1‚ 2‚1.9‚ and 1.4‚ which indicates that the integrated values will be off for some of the peaks. The peak at 2.0 ppm represents standard methyl Hydrogens‚ and the singlet

    carbonyl functional groups share these two properties‚ within the carbonyl family of compounds‚ there are significant differences in reactivity. Aldehydes are generally more reactive than ketones and more easily oxidized. Carbonyls directly bonded to aromatic groups are generally less relative than Carbonyls that are directly bonded to alkyl substituents. In this experiment‚ we will perform each reaction on the known compounds that correspond to each chemical test first‚ to determine whether the

    Hydrocarbons – Methane (Alkanes) Introduction to Hydrocarbons – Methane Carbons have the ability to form many different compounds. Compounds of carbon that only contain carbon and hydrogen are known as hydrocarbons. Most hydrocarbons naturally occur in the mixture crude oil. There are three main types of hydrocarbons‚ alkanes – saturated hydrocarbons made up of only single bonds‚ alkenes – unsaturated hydrocarbons with one or more double bond/s‚ and alkynes – unsaturated hydrocarbons with one or

    --------------------------------- Morning I know yesterday was a healthy dose of information‚ so today I’ll answer the question I’m most asked about – how did I start making lipstick from food and also chat a little about mineral oils and synthetic hydrocarbons in our beauty and personal care products. Over the last few days you may have been more aware of the amount of chemicals in food‚ and as we head deeper into #28NBR‚ you may be surprised to learn how many synthetic toxic ingredients are added to

    Methyl Benzoate Objectives: -To prepare methyl-3-nitrobenzoate from nitration of methyl benzoate by electropilic aromatic substitution. -To calculate the percentage yield and get the melting point of methyl-3-nitrobenzoate. Introduction: Benzene contains compounds have special properties that make them to react differently than other molecules. The conjugated compound of dienes in aromatic rings give an extra stability to undergo addition reactions

    Part 1. Hydrocarbon Nomenclature From International Union of Pure and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right

    Introduction: The purpose of this lab was to explore the concepts of electrophilic aromatic substitution‚ specifically nitration by synthesizing methyl m-nitrobenzoate using methyl benzoate‚ nitric acid and sulfuric acid. This nitration is a type of electrophilic aromatic substitution. A strongly charged electrophile‚ in this case a nitro group‚ replaces a proton on the aromatic ring. Aromatic compounds undergo substitution instead of addition to maintain resonance. The substituent on the

    1. PETROLEUM TRAPS http://www.usoilandgas.net/findingoil.htm Hydrocarbons - crude oil and natural gas - are found in certain layers of rock that are usually buried deep beneath the surface of the earth. In order for a rock layer to qualify as a good source of hydrocarbons‚ it must meet several criteria. Characteristics of Reservoir Rock For one thing‚ good reservoir rocks (a reservoir is a formation that contains hydrocarbons) have porosity. Porosity is a measure of the openings in a rock‚ openings
