The formula Na 2 SO 3 denotes that the cation is sodium, or Na +, and that the anion is the sulfite ion (SO 2− 3). Therefore, this compound is named sodium sulfite. If the given formula is Ca(OH) 2, it can be seen that OH − is the hydroxide ion. Since the charge on the calcium ion is 2+, it makes sense there must be two OH − ions
Similarly, H 2 O is most often simply called water in English, though other chemical names do exist. Single atom anions are named with an -ide suffix: for example, H − is hydride. Compounds with a positive ion : The name of the compound is simply the cation's name (usually the same as the element's), followed by the anion.
The main group elements are the elements of groups 1, 2, and 13–18 (i.e. the s-block and p-block). [5] The transition elements are the elements of groups 3–12 (i.e. the d-block) – this in particular includes group 12 (although some sources do not include it). [5] The inner transition elements are f-block elements. [2]
The suffixes -diol, -triol, -tetrol, etc., are used for multiple −OH groups: Ethylene glycol CH 2 OHCH 2 OH is ethane-1,2-diol. If higher precedence functional groups are present (see order of precedence , below), the prefix "hydroxy" is used with the bonding position: CH 3 CHOHCOOH is 2-hydroxypropanoic acid.
For example, the sodium benzoate is an ionic compound with the structure C 6 H 5 –CO–O − Na +, and its condensed structural formula usually written as C 6 H 5 CO 2 Na. The suffix comes from "-oic acid". The most common examples of compounds named with the "oate" suffix are esters, like ethyl acetate, CH 3 COOCH 2 CH 3.
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
