WebAddition polymerisation of alkenes. An addition polymer is a long-chain molecule with a high molecular mass, made by joining together many small molecules called monomers: MANY MONOMERS → SINGLE POLYMER. n molecules → 1 single molecule. The monomer used is an unsaturated alkene containing a double C=C bond. WebHigher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane …

The position of the double bond It is indicated by inserting before the suffix -no the Latin prefix that indicates the number of the carbon where the double bond begins (di (2), tri (3), tetra (4), penta (5), octa (8), etc. ). WebAlkene formation in E1 reactions is not stereospecific. After the leaving group leaves, there is time for rotation about the Cα-Cβ bond to occur in the intermediate carbocation before ethanol (acting as a base) removes a β -H from that carbocation. As a result, the alkene product is a mixture of the two possible stereoisomers. Figure 9.11 daad wise internship germany 2022
