Answer» 2-fluorohexane `underset(C_(2)H_(5)OH)OVERSET(C_(2)H_(5)O^(-))to` 2-chlorohexane `underset(C_(2)H_(5)OH)overset(C_(2)H_(5)O^(-))to` 2-bromohexane `underset(C_(2)H_(5)OH)overset(C_(2)H_(5)O^(-))to` 2-iodohexane`underset(C_(2)H_(5)OH)overset(C_(2)H_(5)O^(-))to` Solution :Fluoro alkene gives mainly Hofmann product due to E1cB mechanism
