  • The Principles Of The Octet Rule, Electronegativity, Polarity

    electrons to complete its valence electrons when they form molecules. Atoms can share electrons to satisfy the octet rule. This is called a molecular bond. In a molecular bond, the shared electrons create a bond between atoms which is called a bonding pair. Paired atoms which are not shared are called lone pairs. Electronegativity is the likelihood of an atom to attract an electron pair to itself in a molecular bond. The atoms which are closer to having eight electrons are much more likely…

  • Lab Report Cyp1a1

    Additionally recent studies indicate that this enzyme is highly contributed in the detoxification and protection of the organs or parts of the body that are exposed to carcinogens chemicals. For example, it has been found that this enzyme is highly active in smokers than the non-smokers in order to metabolize the chemicals in lungs however the exact function of this enzyme in lungs is not determined yet. In fact it has been found that CYP4501A1 has this type of protective function in skin and…

  • P Toluidine Synthesis Analysis

    It must be synthesized using several, sequential chemical reactions. Benzocaine is useful as a mild topical anesthetic that is the active ingredient in many anesthetic ointments such as Orajel for teething relief and Solarcaine, for sunburn relief. The four step synthesis of benzocaine (ethyl 4-aminobenzoate)…

  • Two Major Limitations Of Molecular Orbital Theory (MOT)

    energy (ii) overlap one another as much as possible (iii) have the same symmetry with respect to bonding molecular axis. 4. Ligand Field Theory (LFT): LFT is a more comprehensive and sophisticated theory is now evolved from the combination of CFT and MOT. Cotton defined LFT as the theory of the origin and the consequence of the splitting of the inner orbitals of transition metal ions and their chemical environment. The CFT assumes that the orbitals of the ligand atom do not overlap with the…

  • Reaction Between Propanone And Sulfuric Acid

    The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

  • Beer Lambert Law Lab Report

    absorbing species is too high, the relationship between absorbance and concentration is non-linear. the reason is because5; 1. At high concentrations, the interactions with the solvent and other solute molecules change 2. At high concentrations hydrogen bonding interactions occur which interact differently with the other…

  • Importance Of Coordination Compounds

    electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate covalent bond is a covalent bond in which one atom (i.e., the donor atom) gives both electrons. This type of bonding is different from a normal covalent bond in which each atom supplies one electron. • If the coordination complex carries a net charge, the…

  • Methane-To-Methanol Reaction Report

    A. Defining Reaction Mechanisms and Catalyst Structure The methane-to-methanol reactions that we aimed to evaluate consist of four critical steps starting from the initial reactants (CH4, NH4+, oxo): C-H activation followed by a hydrogen atom abstraction (HAA) from CH4 to form some combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via…

  • Analysis Of Mulliken Atomic Charges Analysis

    3.3. Mulliken Atomic charges analysis Mulliken atomic charge calculation has an important physical property of the quantum chemical calculation of molecular system because of the atomic charge effect, electronic structure and more a lot of properties of molecular systems [19].The possible molecular bonding of a compound depends on the electronic charge existing on the chelating atoms [20]. The charge changes with basis set presumably occur due to polarization. The charge distribution of (C20 is…
