What is CH2 unit?
As with alkanes, alkenes form a homologous sequence of molecules that increase molecular weight by adding units of
methylene
(–CH2–). If the double bond is at the end of a molecule it is called a terminal alkene.

What is H3C chemistry?
Answer:CH3- is the symbol
fro methyl group
. H3C is also a symbol for the same. It is sometime written this way to show the direct bonding between the carbon and its neighbouring atom on the right hand.
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.
Is CH2 an electrophile?
CH2 act as electrophile as
it is short of electrons
. … Since CH2 has only 6 electrons that is 2 electron short so show affinity towards electron pair and hence can accept the pair of electrons, so act as an electrophile.
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.
What is the general formula for alcohols?
The general formula for the alcohols is
C
n
H
2n + 1
OH
(where n is the number of carbon atoms in the molecule).
What is the homologous series of alcohol?
The alcohols are a homologous series of
organic compounds
. They all contain the functional group –OH, which is responsible for the properties of alcohols. The names of alcohols end with ‘ol’, eg ethanol. The first three alcohols in the homologous series are methanol, ethanol and propanol.
What is alkenes general formula?
Alkenes are defined as either branched or unbranched hydrocarbons that possess at least one carbon–carbon double bond (CC) and have a general formula of
CnH2n [1]
.
Whats the difference between H3C and CH3?
Answers and Replies
There’s no difference
. Sometimes it’s more convenient to write the three hydrogens on the left side of the carbon and sometimes its more convenient to write the hydrogens on the right side of the carbon.
What is the name of H3C CH3?
Straight chain hydrocarbons are named according to the number of carbon atoms: CH4, methane; C2H6 or H3C-CH3,
ethane
; C3H8 or H3C-CH2-CH3, propane; C4H10 or H3C-CH2- CH2-CH3, butane; C5H12 or CH3CH2CH2CH2CH3, pentane; C6H14 or CH3(CH2)4CH3, hexane; C7H16, heptane; C8H18, octane; C9H20, nonane; C10H22, CH3(CH2)8CH3, …
What is the name of CS2?
Carbon Disulfide
(CS2) is a colorless. dense, highly refractive, volatile, flammable and toxic liquid.
How is CH2 formed?
CH
2
-Species were formed
on a cobalt catalyst by the Boudouard reaction or by the decomposition of methane
; hydrogenation yielded methane as well as α-Olefins, while the hydrogenation of carbidic carbon yielded merely methane.
