Polymerisation of alkenes
WebPolymerisation of Alkynes Like alkenes, alkynes also undergo polymerisation reactions. For example, linear polymerisation of ethyne under suitable conditions produce polyacetylene (polyethyne) having formula − (C 2 H 2) n −. It may be noted that the repeating units of polyethyne are − (CH═CH−CH═CH) n −. WebWhat is the general formula of alkenes? CnH2n. What is the functional group of alkenes? C=C.
