C is best methode Bromination of alkane is most favourable due to lessbond disassoction energy between C and Br moleculesafter substution of halogens ( Acctuvally I2 has less butit is revesable reaction) Order of I2 ? 2I* Alkylhalide on treated with NaOCH3 gives alkenes Solution C is best methode Bromination of alkane is most favourable due to lessbond disassoction energy between C and Br moleculesafter substution of halogens ( Acctuvally I2 has less butit is revesable reaction) Order of I2 ? 2I* Alkylhalide on treated with NaOCH3 gives alkenes.
