The peak at 480.28 cm1 for NCHB-PLA/PHA is characterized as the =CH bending bond structure from the functional group of alkenes. The DSC result prove that the reduction in the crystallinity values was an indicator of improvement in the adhesion between fiber and polymer in the bio-composites...

Isofunctional reactions involving C=C cleavage have become practical synthetic strategies because they not only permit the restructuring of the carbon chain structures of alkenes, but also allow the exchange of functional groups without the introduction of exogenous groups [6,7]. To date, these ...
These addition reactions are analogous to those of the alkenes. Alkenes are unsaturated molecules, which means they do not have all the hydrogen they could have. This is because there is at least one double bond between carbons. This is a stable structure, but not the most stable, so when...

bromides 11 and alkyl chlorides 12 were also well tolerated in the room temperature process (94%, 65% and 89% yield respectively) whilst diminished yields were observed at higher temperature consistent with elimination or other side-reactions (see incompatibility of mono-substituted alkenes such as...
Alkenes Organic compounds are termed alkenes if they contain a carbon-carbon double bond. The shared electron pair of one of the bonds is a σ bond. The second pair of electrons occupies space on both sides of the σ bond; this shared pair constitutes a pi (π) bond. A π bond forms...

alkynes have priority over alkenes. During nomenclature of long chain carbon compounds, numbering done in such a way as to locate double or triple bond by shortest route. Doesn’t matter which functional group arrive first. In any way alkynes are preferred over alkenes. Reply James Ashenhurst ...
cis-Alkenes are 1,2-disubstituted functions with the two R, X or other groups on the same side of the C=C function. Due to the non-rotation of the C=C bond, cis and trans geometric isomers are not [thermally] Interconvertion. Ether Ethers have a pair of alkyl or aromatic groups at...
