The sequence of reagents in option B, which involves using sodium acetylide and excess hydrogen sulfide, followed by catalytic hydrogenation with Pd/C, is the best choice for converting 1-bromobutane to hexane. Option A involves using sodium ethoxide and sodium cyanide, which are less effective at achieving the desired transformation. Option C involves using sodium hydroxide and a dehydration agent followed by hydrogenation, but this can result in side reactions and lower yields. Option D involves using sodium cyanide and borane, which can produce hazardous by-products. Option E also uses sodium acetylide, but this is followed by the less effective sodium amide.
