Multiplicity Details 7.2-7.4 1 Multiplet These peaks are indicative of hydrogen’s from the benzene rings. Since there are two of them in the molecule‚ there are two sets of hydrogens that are similar in energy and will split each other from the other set. 4.8 1 Singlet I believe this peak is coming from the hydrogen connected to the carbon that also connects to the anhydride ring. It is deshielded by the neighboring benzene rings. 3.5 1 Singlet This peak is coming from the hydrogen attached to the anhydride

Introduction Background Indicators are used in acid-base titrations to determine end points as both acid and base are colourless in nature. However‚ indicators chosen must be suitable according to the type of reactions such as: - Strong acid-weak base titration - Weak acid-strong base titration - Strong acid-strong base titration - Weak acid-weak base titration Only the first two mentioned above will be investigated in this experiment. Aims/Objectives 1. To understand

chromatogram/spectrum peak report it is shown that there are two retention times of 15.67 and 9.66. The first peak has 9.66 retention time and has one possible match out of the five which is included in appendix 1.The highest match is ecgonidine‚ methyl ester (EDME) with 944 match and a 953 reverse match. EDME is a product of the thermal decomposition of cocaine and has been identified as a likely candidate for the detection of concealed cocaine (Analytical Chemistry 1997). The second peak‚ which

When butane’s dihedral angle was at 0⁰ and 360‚ the conformations are at an Emax. This means that the two methyl groups are eclipsed. At 60⁰ and 300⁰‚ which have gauche conformations‚ the methyl groups are more shifted and the potential energy difference is 18.2 kj/mol. At 120⁰ and 240⁰‚ eclipsed again‚ the energy rises to -4.6788 kj/mol‚ from its previous -17.721 kj/mol‚ the hydrogens can be found lying on the same plane‚ increasing the energy. Yet‚ the energy is not as high as it is at 0⁰ and 360⁰

Oil-soluble compounds include sulfides‚ such as diallyl sulfide (DAS)‚ diallyl disulfide (DADS)‚ diallyl trisulfide and allyl methyl trisulfide‚ dithiins‚ and ajoene. Water-soluble compounds include cysteine derivatives‚ such as S-allyl cysteine (SAC)‚ S-allyl mercaptocysteine (SAMC) and S-methyl cysteine‚ and gamma-glutamyl cysteine derivatives. Oil-soluble sulfur compounds are odorous‚ whereas water-soluble compounds are odorless. Moreover‚ water-soluble compounds

Fatty acids (FAs) can ultimately be degraded through different pathways which include alpha‚ beta‚ and omega-oxidation. Alpha-oxidation occurs at carbon 2 of the chain‚ b-oxidation at C3‚ and omega-oxidation at methyl end of the fatty acid. The location of each mechanism also differs as alpha- oxidation occurs in peroxisomes only‚ beta-oxidation can take place in both peroxisomes and mitochondria. Omega-oxidation occurs in the endoplasmic reticulum of the various tissues. The importance of the differentiation
