Originally the second of three degrees in sequence – Legum Baccalaureus (LL.B., last conferred by an American law school in 1970); LL.M.; and Legum Doctor (LL.D.) or Doctor of Laws, which has only been conferred in the United States as an honorary degree but is an earned degree in other countries. In American legal academia, the LL.M. was ...

Note that "group" has a chemical meaning and "column" has the tabular meaning. Alternatively, they may be named by their first element, e.g. "boron group" for group 13. [2] (But per below, avoid iron group for group 8 as ambiguous.) In the 1–18 scheme, f-block groups are unnumbered.
If four oxyanions are possible, the prefixes hypo-and per-are used: hypochlorite is ClO −, perchlorate is ClO − 4. The prefix bi-is a deprecated way of indicating the presence of a single hydrogen ion, as in "sodium bicarbonate" (NaHCO 3). The modern method specifically names the hydrogen atom.
Chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)
Alternatively, more explicit structure-based nomenclature can be used when the polymer structure is proven. Where there is no confusion, some traditional names are also acceptable. Whatever method is used, all polymer names have the prefix poly, followed by enclosing marks around the rest of the name. The marks are used in the order: {[( )]}.
