71-43-2Okwu mmalite: Ịghọta ihe ọ pụtara
N'ihe gbasara ogige, "71-43-2" na-ezo aka n'otu ihe akpọrọ benzene. Benzene bụ hydrocarbon na-esi ísì ụtọ bụụrụ isi nkuku nke kemịkalụ organic kemgbe achọpụtara ya na mmalite narị afọ nke 19. Usoro molekụla ya C6H6 na-egosi na ọ bụ carbon carbon isii na atọm hydrogen isii ahaziri n'usoro mgbanaka atụmatụ nwere nkwụsi ike.
Ihe kpatara benzene ji dị mkpa abụghị naanị n'ihi ihe ndị nwere kemịkal pụrụ iche, kamakwa n'ihi na a na-ejikarị ya eme ihe n'ụlọ ọrụ dị iche iche.
