HTTP/2 with Conncurrency is a protocol that allows multiple requests and responses to be multiplexed over a single connection. This improves performance and efficiency compared to the older HTTP/1.1 protocol.
H2C=C(CH3)COOCH3
An alkene has a double bond between its carbon atomsE.g H2C=CH2 This is an ethene molecule, the simplest of alkenes.
NO!!! You do NOT break monomers. However, monmers have a carbon/carbon double bond. One bond of this double bond breaks to give two 'loose ends'. These loose ends then combine with the loose ends of another mon0mers to form a polymer. Monomer + monomer = polymer. H2C=CH2 + H2C=CH2 = -[-CH2-CH2-CH2-CH2-]-(n) H2C=CHCl + H2C=CHCl = -[-CH2-CHCl-CH2-CHCl-]-(n) These polymers are named 'polyethylene/polychloroethen (polythene / PVC). NB THere are many different polymers. NB The product polymer is normally written is this way, because in polymerisation thousands if not millions of monomer molecules combine. The 'n' stands for any number in the chain .
It is 2,4-dinitrophenylhydrazine with the chemical formula C6H6N4O4.
Formaldehyde, H2C=O, is the basic member of organic compounds known as aldehydes. Aldehydes are hydrocarbons (chains of carbons with hydrogen attached) with an oxygen atom double-bonded to a carbon.

A classic example is ethylene: H2C=CH2.
H2C=C(CH3)COOCH3
There are 5 sigma bonds and 1 pi bond in the molecule H2C=CH2. The sigma bonds are the single bonds between the carbon atoms and hydrogen atoms, and the carbon atoms are connected by a double bond which consists of 1 sigma bond and 1 pi bond.
A double bond is a covalent bond where 4 electrons are shared as in H2C=CH2
No such chemical as ' polyethane'. I think you means 'POLYETHENE', note the spelling. Polythethene contains only two elements, viz. hydrogen and carbon. The monmer is ethene (H2C=CH2). This monomer breaks at the double bond to form polyethene. It is represented by the symbol . -[-H2C - CH2-]- (n) NB Polyvinylchloride contains three elements. viz. carbon, hydrogen and chlorine. #The monomer is H2C=CHCl The polymer is represented by -[H2C- CHCl-]-(n)
An alkene has a double bond between its carbon atomsE.g H2C=CH2 This is an ethene molecule, the simplest of alkenes.
A tricglyceride is a glyceride occurring naturally in animal and vegetable tissues; it consists of the esters of three fatty acids on a glycerin "backbone". Its chemical structure looks like this: H2C - O - CO - R1 | HC - O - CO - R2 | H2C - O - CO - R3 Here, each of the R parts is a hydrocarbon tail (possibly with side branches or double bonds). A triglyceride is made by combining glycerine with fatty acid. Glycerine looks like this: H2C - OH | HC - OH | H2C - OH and a fatty acid is like this: R - COOH
The compound is 1-propanol, which is a type of alcohol. It consists of a propyl (3-carbon) chain with a hydroxyl group (-OH) at the end.
The chemical formula for vinyl chloride is C2H3Cl, or in semi-structural notation, H2C=CHCl.

Butadiene has two resonance structures due to the delocalization of electrons between the two double bonds. The first resonance structure has alternating single and double bonds, while the second has a double bond on one end and a single bond on the other. These resonance structures contribute to the stability of the molecule.
