Q:Why does the molecular atom compound do not belong to the life structure: Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond

Q:Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.

Q:Peracetic acid is not: A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered

Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.

Q:Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok

Q:Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: Red coral is not absorbed red, so it looks red.

Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Pro-butylbenzene ethane

Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Not a polymer can not be considered a saturated hydrocarbon derivatives. Natural oils contain unsaturated structures

Q:What is the difference between crude oil and asphalt?: Financial institutions, financial management, cash exchange, the exchange of foreign exchange private schools

Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?: From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.
