Q:What are the nature of sugar
Carbohydrates are composed of carbon, hydrogen and oxygen three elements, because it contains the proportion of hydrogen and oxygen for two to one, and water, it is called carbohydrates. It is the body to provide heat for the three main nutrients in the cheapest nutrients. Carbohydrates in food are divided into two categories: people can absorb the use of effective carbohydrates such as monosaccharides, disaccharides, polysaccharides and people can not digest the ineffective carbohydrates such as cellulose, which is essential for the human body.
Q:Does the carboxylic acid react with the Grignard reagent?
Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.
Q:Who knows which organic intermediates are good?
Tianjin Chi Sheng Trading Co., Ltd. is a professional engaged in domestic and international sales of chemical products business, after years of development, the company's business involves medicine, petrochemical, lubricants, coatings, dyes and other industries. With a complete technical support and staffing, product market is vast, sold all over the country. The company's main organic intermediates, pharmaceutical intermediates, chemical solvents and chemical additives four categories of hundreds of varieties.
Q:What cells are composed of compounds
Protein and water
Q:Sodium can be used to identify derivatives of hydrocarbons
Sodium can identify hydrocarbon derivatives that are alcohol
Q:The main role of sugar?
The energy of life
Q:Derivatives of vinyl acetate
Vinyl acetate can produce reactions that occur most of the olefins or esters. Such as the addition of bromine to form dibromide, the addition of hydrogen halide to produce vinyl haloacetate, which is the only way to produce the substance because there is no corresponding halohydrin. The addition of acetic acid under palladium catalysis can produce ethylene diacetate and CH3CH (OAc) 2. The latter can undergo a transesterification reaction with many carboxylic acids. As an alkene, vinyl acetate can also undergo a Diels-Alder reaction and a 2 + 2 ring addition
Q:Is carbon monoxide an organic gas?
Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.
Q:What is the definition of organic matter
Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
