List of chemical compounds with unusual names

Chemistry is said to be a subject mostly comprising of reactions along with formulas. We come across various chemical substances in our daily life. Some of the substances we use in our house such as the staples present in the medicine cabinet comprise chemical substances. Chemical Formula in Chemistry is like a shorthand used to represent the elements in a compound. The Periodic Table has elements along with the symbols. These Chemical symbols are used for representing different individual elements like H is hydrogen, O for oxygen, Ca for calcium, Na for Sodium and so on.

Generally questions from the topic Common Names and Formulas of Important Chemical Compounds are asked in every competitive exam. Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. A compound is a substance made up of a definite proportion of two or more elements. With the help of Chemical formulas, you can check number of atoms and elements in the compound.

Approximately one-third of the compounds produced industrially are organic compounds. All living organisms are composed of organic compounds, as are most foods, medicines, clothing fibers, and plastics. The detection of organic compounds is useful in many fields. By analyzing these organic gases and isolating the individual components, preservationists are better able to determine the condition of an object and those books and documents most in need of immediate protection. The simplest class of organic compounds is the hydrocarbons, which consist entirely of carbon and hydrogen. Petroleum and natural gas are complex, naturally occurring mixtures of many different hydrocarbons that furnish raw materials for the chemical industry. The four major classes of hydrocarbons are the following: the alkanes, which contain only carbon—hydrogen and carbon—carbon single bonds; the alkenes, which contain at least one carbon—carbon double bond; the alkynes, which contain at least one carbon—carbon triple bond; and the aromatic hydrocarbons, which usually contain rings of six carbon atoms that can be drawn with alternating single and double bonds.

This is a list of common chemical compounds with chemical formulae and CAS numbers , indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.

The empirical and molecular formulas discussed in the preceding section are precise and informative, but they have some disadvantages. First, they are inconvenient for routine verbal communication. In such cases, it is necessary for the compounds to have different names that distinguish among the possible arrangements. Many compounds, particularly those that have been known for a relatively long time, have more than one name: a common name sometimes several , and a systematic name, which is the name assigned by adhering to specific rules. Like the names of most elements, the common names of chemical compounds generally have historical origins, although they often appear to be unrelated to the compounds of interest.

Chemical nomenclature , replete as it is with compounds with complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics a fundamental resource will reveal not just the whimsical work of chemists , but the sometimes peculiar compound names that occur as the consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer. Some are given intentionally unusual trivial names based on their structure, a notable property or at the whim of those who first isolate them.

Ndakota… Kadotan… Oktadan… Tandoka… Сьюзан почувствовала, как ноги у нее подкосились. Стратмор прав. Это просто как день. Как они этого сразу не заметили.

Он получал информацию со 148 камер кабельного телевидения, 399 электронных дверей, 377 устройств прослушивания телефонов и еще 212 жучков, установленных по всему комплексу АНБ. Директора АН Б дорого заплатили за осознание того факта, что двадцать шесть тысяч сотрудников не только огромная ценность, но и источник больших неприятностей. Все крупные провалы в сфере безопасности в истории агентства происходили внутри этого здания. В обязанности Мидж как эксперта по обеспечению внутренней безопасности входило наблюдение за всем, что творилось в стенах АНБ… в том числе и в кладовке столовой агентства.

Халохот поднимался вверх с пистолетом в руке, прижимаясь вплотную к стене на тот случай, если Беккер попытается напасть на него сверху. Железные подсвечники, установленные на каждой площадке, стали бы хорошим оружием, если бы Беккер решил ими воспользоваться. Но если держать дистанцию, можно заметить его вовремя.

Сьюзан положила голову ему на грудь и слушала, как стучит его сердце. А ведь еще вчера она думала, что потеряла его навсегда. - Дэвид, - вздохнула она, заметив на тумбочке его записку.  - Скажи мне, что такое без воска. Ты же знаешь, что шифры, которые не поддаются, не выходят у меня из головы.
