The English-language chemistry examination for Plovdiv Medical University<\/a> contains the following entrance examination syllabus.<\/p>\n The candidate should be prepared for the following:<\/strong><\/p>\n<\/div>\n<\/div> Atomic structure Atomic number, atomic nucleus, atomic mass, isotopes and isobars. Electronic structure of the atom – energy levels, characteristics of s-, pan- d-orbitals. Electronic configuration and orbital diagram of the elements of I and II period of the periodic table. Periodic trends – atomic radius, ionization energy, electronegativity, elements with metallic and nonmetallic character. <\/p>\n 2.Chemical bonding Ionic bond. Covalent bond – types (polar, nonpolar) and characteristics (bond energy and length, direction); coordinate (dative covalent) bonding. Metallic bond, hydrogen bond, Van der Waals forces. <\/p>\n Rate of chemical reactions Kinetic equation, rate constant. Energy diagram of a reaction: activation energy, exothermic and endothermic reactions. Factors affecting rate of reaction – state of reactants, temperature, concentration, pressure. Rate determining step of a reaction. Catalysis – properties of catalysts. Mechanism of homogeneous and heterogeneous catalysis. <\/p>\n 4.Chemical equilibrium Reversible reactions, state of equilibrium. Equilibrium constant. Factors affecting chemical reactions in equilibrium. Effect of concentration and pressure change, effect of temperature and catalysts. Le Chatelier’s principle. <\/p>\n 5.Solutions Types of solutions (saturated, supersaturated, unsaturated). Concentrations of solutions (mass and volume concentration, molar concentration, molality). Factors affecting the solubility of solid, liquid and gas compounds in liquids (nature of the solvent and solute, temperature, pressure). Properties of solutions that depend upon the concentration of solute (vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure). <\/p>\n 6.Electrolytes Weak and strong electrolytes, degree of dissociation. Theories of acids and bases (Arrhenius theory, Br\u00f8nsted-Lowry theory, Lewis theory). Ionization of water – pH scale. Hydrolysis of salts. <\/p>\n Oxidation-reduction reactions Basic concepts: oxidation number, oxidizing and reducing agents, oxidation and reduction, balancing oxidation-reduction reactions. Oxidizing and reducing properties of elements. Electrolysis – practical application. <\/p>\n<\/div>\n<\/div> 8 Properties of metals and nonmetals Reactivity series of metals, reactions with dilute acids, oxygen, nonmetals, water, acids and salts Reactions of nonmetals with oxygen, hydrogen, other nonmetals, metals and salts. 11. basic concepts Hybridization of carbon atom. sigma- and pi-bonds; single, double and triple bonds. structural and stereoisomerism of organic compounds. general principles of IUPAC nomenclature for naming organic compounds.
