Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.

Q: Organic organic compounds are organic matter?: Your teacher said, "organic polymer compounds are a mixture," this sentence itself is contradictory ... ... compounds are mixed? The He was wrong it 囧,

Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?: The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.

Q: What are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?: For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: There are many kinds of oxygen-containing derivatives of alcohols which can be classified into alcohols, phenols, aldehydes, carboxylic acids and esters, etc. The nature of the oxygen-containing derivatives of hydrocarbons is determined by the functional groups, and the nature of the organic compounds can be used to synthesize the oxygen- There is no organic matter to meet our needs.

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbon must be even.

Q: NH4HCO3 and so have C atoms ah, why still inorganic: Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.

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: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.

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: China's chemical name may be the best of both Latin and English
