Answer :
Word Count : 267
The common laboratory route to decaborane, B₁₀H₁₄, from the pentaborane(−) fragment uses oxidative cage-fusion of two pentaborane units. In practice the lithium or sodium salts of the pentaborate anion, M\[B₅H₈] (M = Li, Na, K), are oxidized (chemical oxidants such as FeCl₃, NiCl₂, Br₂ or alkyl halides have been used) and the two __________ ____ _________ __________ ________ _________ __________ ____ ______ __________ ___.
