The hydrogen molecule consists of two protons held together by a pair of electrons. These forces just balance when the nuclei are a particular distance apart. Co-ordinate bonding A single covalent bond consists of a pair of electrons shared between two atoms. In most covalent bonds, each atom provides one of the electrons. But, in some Bonds, one atom provides both the electrons.
C) excess electrons. D) filled shells. E) lone pairs. 5. In forming covalent bonds where the octet rule is obeyed, sulfur usually forms ________ bonds and chlorine usually forms ________ bonds.
The suffix –ine is used for amino acids, and the suffix –yl is used for the protein’s structure. Carbon needs to create bonds; in any way it can, with other atoms. It can share its electrons with up to 4 other atoms at once, which lets carbon build complex chains. Carbon is very similar with silicon, the element right under it. Silicon has the capability to imitate carbon, and constantly bonds with oxygen.

Introduction: The radical chlorination of chlorobutane results in the formation of four possible products. These products are formed by substitution reactions, where a halogen atom (chlorine) replaces a hydrogen atom (Wade 2010). The amount of each product formed is based on the relative reactivity of the product. The calculations of the relative reactivity are dependent on the reactivity of the hydrogen atoms, which is influenced by the chloro substituent as well as other factors such as the level of the substituted carbon and the bond dissociation energy. For this lab we want to observe how the chloro substituent has an effect on the reactivity of the possible hydrogen atoms.
dispersion forces occur frequently for short periods of time. Dipole force - this permanent force operates between polar molecules. - a polar molecule has regions of positive and negative charge. Hydrogen bond - highly polar bond capable of producing a strong dipole force between molecules. the dipole attraction is typically about 10% of the strength of a normal covalent
Hydrogens on the alkene have different reactivity which determines which isomer is favored. Hydrogens attached to carbons, and have a weak bond strength are most reactive therefore are favored during abstraction by chlorine. The chloro substituent has an effect on carbon reactivity due to the chlorine atom being an electron withdrawing substituent. The chlorine
