Alkyl Halides Alkyl halides are a class of compounds where a halogen atom or atoms are bound to an sp3 orbital of an alkyl group. CHCl3 (Chloroform: organic solvent) CF2Cl2 (Freon-12: refrigerant CFC) CF3CHClBr (Halothane: anesthetic) Halogen atoms are more electronegative than carbon atoms‚ and so the C-Hal bond is polarized. H H μ C + C-l δ δ H The C-X bond is polarized in such a way that there is partial positive charge on the carbon and partial negative charge on the halogen. Dipole moment

Differentiate between the significance of the coefficients in a balanced chemical equation and the significance of the subscripts in a chemical formula. · Coefficients show the correct proportions of atoms and molecules in a chemical reaction. They are normal sized numbers placed at the beginning of the chemical formulas in a chemical reaction during the process of balancing. They tell how many of an entire

ABSTRACT: Skeletal muscle is able to repair itself through regeneration. However‚ an injured muscle often does not fully recover its strength because complete muscle regeneration is hindered by the development of fibrosis. Biological approaches to improve muscle healing by enhancing muscle regeneration and reducing the formation of fibrosis are being investigated. Previously‚ we have determined that insulin-like growth factor–1 (IGF-1) can improve muscle regeneration in injured muscle. We also

Frog Skeletal Muscle The aim of this experiment is to explore the basic physiological principles of skeletal muscle using the isolated frog (Rana pipiens or Xenopus laevis) gastrocnemius muscle. Students will dissect a double-pithed frog. Then‚ they will connect the muscle to the Force Transducer to measure twitch recruitment‚ effect of stretch‚ muscle summation‚ muscle tetanus‚ and muscle fatigue. Written by staff of ADInstruments.

The general electronic configuration of transition metal is (n–1) d1–10ns1–2. Exceptions in electronic configuration are due to (a) very little engery difference between (n–1) d and ns orbitals and (b) extra stability
