Halogens, elemental bonds

Formation of the Group-IIIB-Group-IIIB Element Bond 6.2.5. from Gallium in Halogen Acid Media... 

The most widely used method for the synthesis of iminoboranes involves the 1,2-addition of boron-element bonds such as boron-hydrogen, boron-halogen, boron-carbon, or boron-sulfur bonds across the C=N bond of nitriles thereby producing variously substituted iminoboranes (Eq. (2)). The formation of iminoboranes as well as the stability of the products depends on the substituent on the nitrile group, the nature of the boron-element bond to be cleaved during the 1,2-addition across the C N bond, and to a lesser extent on the non-reacting boron substituents 26T... 

Br, and I (but not F) for example, hydrochloric acid, HCl, and hydrobromic acid, HBr (HCl and HBr are hydrohalic acids acids that have hydrogen bonded to atoms of the halogen elements.)... 

The dipole moments of hydrogen halides decrease with the period of the halogen element the increase in the bond length / is overpowered by the decrease... 

Carbon atoms form bonds readily with hydrogen, oxygen, and nitrogen. Carbon also may combine with halogen elements (fluorine, chlorine, bromine, iodine), with phosphorus and sulfur, and, less often, with other elements. 

The conventional As and As compounds have As—C single bonds and are based upon AsRa and AsRs and their substituted variants with halogens, oxide, etc. In addition, there have been significant recent developments in the chemistry of compounds containing homo-element bonds... 

The cleavage of carbon-group-VIB, -VB or -IVB element bonds to give organolithiums is directly analogous to the Li cleavage of carbon-halogen bonds (see 5.5.2.2.1) ... 

T n organizing the symposium upon v/hich this book is based, we brought together a diverse group of scientists whose common bond was an interest in radiochemistry, primarily with short-lived nuclides of carbon, nitrogen, oxygen, and the halogen elements.
