Determination of hydrocarbon groups in chemistry, various hydrocarbon group chemical formulas

Hello, the hydrocarbon group refers to the functional group that contains only two atoms, carbon and hydrogen, which should be easier to judge.

It would be nice to name it according to the number of c atoms on this linked group.

It is important to note that halogenated hydrocarbons do not belong to the hydrocarbon group.

As long as it contains -OH, it is a hydrocarbon group, but the type is different.

1.Hydrocarbon groups. It refers to the group foregrip containing only two atoms of carbon and hydrogen, and generally refers to the loss of one hydrogen atom by the corresponding hydrocarbon.

h) after the remaining free radicals.

2.There are many types of hydrocarbon groups, monovalent saturated groups are also known as alkane nucleus disordered groups, monovalent unsaturated groups are also known as alkene groups and alkyne groups, divalent groups are also called subunits, and trivalent groups are also called secondary groups.

3.Monovalent groups: propyl, butyl, amyl, vinyl, propynyl, cyclopentyl, cyclopropenyl, cyclopropyl.

4.Divalent group, trivalent group: ethylene, subethyl, vinyl, diphenylcarbene, methylene.

Methyl and ethyl groups are the two most common hydrocarbon groups.

Methyl: -ch3;Ethyl: -c2h5. Propyl is a hydrocarbon-based functional group.

The chemical formula is -C3H7 and is abbreviated as PR. There are two isomers of propyl groups: n-propyl (-ch2ch2ch3) and isopropyl (-ch(ch3)2). In addition, "cyclopropyl" is also a substituent of three carbons.

Inorganic mercury, such as metallic mercury and divalent ionic mercury, is converted into methylmercury and dimethylmercury by organisms, especially microorganisms.

This transformation is called biomethylation. The reverse process of this transformation is called biological demethylation. These two actions make up the mercury cycle of microorganisms.

Apply. With the development of molecular genetics, the ecological study of biomethylation and microbial mercury resistance has been pushed to the molecular level, and the genetic control of microbial conversion of mercury has been carried out in recent years. A 1979 study pointed out that the mercury resistance of bacteria is regulated and controlled by genetic plasmids and chromosomes, and that some bacterial plasmids with mercury resistance have the potential to be translocated, so that non-resistant bacterial cells can gain resistance.

This will further clarify the basis for the migration and transformation of mercury by bacteria in the sediment and the recycling of mercury in waste. In order to improve the mercury resistance of microorganisms, some scholars suspect that Qiaocha has applied the new technology of cardiac body transfer to obtain a new plasmid (MER plasmid), and the mercury resistance of bacteria with this new plasmid can be increased by about 40 times.

The hydrocarbon group is usually denoted by R. The hydrocarbon group can be divided into monovalent group, divalent group, and trivalent group. For example, the monovalent basis:

CH3CH2—(ethyl), (isopropyl), CHC—CH2—(2-propynyl). Divalent group: CH3CH=(ethylene), —CHCH—(1,2-vinylyl).

In chemistry, hydrocarbon groups are used to refer to functional groups containing only two atoms, carbon and hydrogen, and can be regarded as the free radicals left after the corresponding hydrocarbon loses one hydrogen atom (H).

Simply put, it is a compound composed of hydrocarbons--- the part that remains after the hydrogen atom is removed, which is a hydrocarbon group, which is an organic group.

alkyl group；Hydrocarbon radical hydrocarbon (hydrocarbon) molecule is a group formed by the absence of one or a few hydrogen atoms.

A group formed by the absence of one or a few hydrogen atoms in a hydrocarbon molecule.

Different types of hydrocarbon groups can be obtained from different hydrocarbons. The hydrocarbon group formed by the removal of one or a few hydrogen atoms from the aromatic hydrocarbon nucleus is called the aromatic hydrocarbon group.

Monovalent group CH3CH2—(ethyl)CH C—CH2—(2-propynyl)divalent group CH3CH=(ethylene).

The hydrocarbon is the part that remains after a number of hydrogen atoms have been removed.

An electrically neutral cluster containing only carbon and hydrogen atoms.

The explanation of the term hydrocarbon group is: in chemistry, it is used to refer to a group that contains only two atoms, carbon and hydrogen, and refers to the group left after the corresponding hydrocarbon loses one hydrogen atom h.

The explanation of the term hydrocarbon group is: in chemistry, it is used to refer to a group that only contains two atoms, carbon and hydrogen, and generally refers to the group left after the corresponding hydrocarbon loses one hydrogen atom h of the sail fiber. The pinyin is:

tīngjī。The structure is: hydrocarbon (left and right structure) group (upper and lower structure).

The phonetic pronunciation is: one by one.

What is the specific explanation of hydrocarbon groups, we will introduce you through the following aspects:
