What does CH2 mean?
In organic chemistry, a methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule by two single bonds. The group may be represented as CH 2 <, where the ‘<‘ denotes the two bonds.
Is CH2 a carbene?
These are highly reactive neutral species containing a divalent carbon. It acts as reaction intermediate.In carbenes , carbon atom has four electrons in the valence shell of which two electrons are unshared. :CH 2 (methylene carbene) is parent carbene from which all other carbene compounds are derived.
Is CH2 an alkyl?

What is functional group called?
Chemical properties of an organic molecule is determined not by the whole molecule but by a specific region in it, called the functional group of the molecule. ... That is, the COOH group, called the carboxylic acid group , is the functional group in 1 and 2.
What is the chemical formula of ethanol?
The molecular formula of ethanol is C2H6O , indicating that ethanol contains two carbons and an oxygen. However, the structural formula of ethanol, C2H5OH, provides a little more detail, and indicates that there is an hydroxyl group (-OH) at the end of the 2-carbon chain (Figure 1.1).
What functional group is NH?
| NAME GROUP BIOLOGICAL EXAMPLE | amine : -NH 2 amino acid (e.g., glycine) | detail: (-NH 3 + ) | ketone: -CO- metabolic intermediate (e.g., pyruvic acid) | detail: O || -C- |

Are carbenes nucleophiles?
Carbenes can be classified as nucleophilic, electrophilic , or ambiphilic. For example, if a substituent is able to donate a pair of electrons, most likely carbene will not be electrophilic.
Why does CH2 exist?
Methene ( CH2 ) does not exist because the Carbon’s Octet is not complete , it needs more 2 electrons . When the Carbon shares 2 more of its electrons by 2 hydrogen atoms it becomes CH4 or Methane . If it shares more 2 electrons by 1 carbon atom is becomes C2H2 or ethene.
Why is carbene an electrophile?
Carbenes are electrophiles because the carbon does not have an octet . The carbon has only two bonds and one lone pair. That’s just three electrons, not eight.
Why is alkyl group denoted by R?
Explanation: Historically, the word “radical” was used to refer to a part or portion of a complete molecule. ... When you see something like R−CO2H it means “ any group in which a carbon or hydrogen atom is attached to the rest of the molecule.” So R could be an alkyl group, but not necessarily.
What is ISO alkyl group?
The prefix “iso” is used when all carbons except one form a continuous chain . This one carbon is part of an isopropyl group at the end of the chain. ... The prefix “neo” is used when all but two carbons form a continuous chain, and these two carbons are part of a terminal tert-butyl group.
Is alkyl a functional group?
An alkyl is a functional group of an organic chemical that contains only carbon and hydrogen atoms, which are arranged in a chain. Examples include methyl CH 3 (derived from methane) and butyl C 2 H 5 (derived from butane). They are not found on their own but are found attached to other hydrocarbons.
What is Rx functional group?
It consists of a group of carbon and hydrogen atoms of any size . It is used as an abbreviation since a group of carbon and hydrogen atoms does not affect the functionality of the compound. In some molecules, you will see R, R’, or R” which indicates that the R groups in the molecule can be different from one another.
What are the 7 functional groups?
Hydroxyl, sulfhydryl, carbonyl, carboxyl, amino and phosphate groups .
