heteronuclear diatomic molecule with an ionic bond. The following are examples of heteronuclear diatomic molecules with covalent bonding: Let us look at HBr‚ for example. Hydrogen is on the left side of the stairs that divide metals and nonmetals in the periodic table‚ but ‘’hydrogen is a nonmetal’’. Bromine (Br) is also a nonmetal‚ so HBr is a heteronuclear diatomic molecule with a covalent bond. !!!Lesson Summary __Diatomic molecules__ consist of two atoms that are either from the same element

Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how

solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly soluble such as CH3COOH‚ under acids we have HF‚ H2CO3‚ H2SO3‚ and NH3.While nonelectrolytes are nonpolar covalent compounds such as

Influenza virus is one of the well-explored the pathogens and development of flu vaccine is considered as the most efficient strategy to defense the outbreak. However‚ the variability of the antigen and rapid reassortant of the genetic segments weakens flu vaccine effectiveness. And the protection of flu vaccine could not contribute to clinical treatment when the patients suffer from severe illness. Therefore‚ the study of the interaction between pathogen and host immune response is needed. The Hannover
