1.(CH3)2CHCH2CH2CH3+F2,heat 2. KOC(CH3)2
1.(CH3)2CHCH2CH2CH3+Cl2,heat2.NaOCH2CH3
1.(CH3)2CHCH2CH2CH3+Br2,heat2.NaOCH3
1.(CH3)2CHCh2CH2CH3+I2,heat2.NaOCH2CH3

(CH3)2CHCH2CH2CH3 + Br2, heat 2. NaOCH3

C is best methode
Bromination of alkane is most favourable due to less bond disassoction energy between C and Br molecules after substution of halogens ( Acctuvally I2 has less but it is revesable reaction)
Order of
I2 ¡ê 2I*
Alkylhalide on treated with NaOCH3 gives alkenes
