Answer» A`to`(3) B`to`(5) C`to`(1) D`to`(2) E`to`(4) A. A mixture containing two enantiomers in equal proportions will have zero optical rotation, such a mixture is known as racemic mixture The process of conversion of enantiomer into a racemic mixture is known as racemisation. If an alkyl halide follows `S_(N)1` mechanism then racemisation takes place while if it follows `S_(N)2` mechanism than inversion takes places. B.Chlorobromocarbons are used in fire extinguishers C.In vicinal dihalides, halogen atoms are present on the adjacent carbon atom Bromination of alkenes will give vicinal dihalides. D. Alkylidene halides are named as gem-dihalides. In gem-dihalides halogen atoms are present on same carbon atom E.Elimination of HX from alkylhalide follows Saytzeff rule. This rule states that "in dehydrohalogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the doubly bonded carbon atoms". |
