Okwu mmalite

Ọkpụkpụ nke dibromomethane. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke dibromomethane:

 

Ogo:

Ọ nwere isi na-esi ísì ụtọ n'ime ụlọ ma ọ bụ ihe a na-adịghị ahụkebe na mmiri, ma soluble n'ọtụtụ ihe mgbaze organic nkịtị.

Dibromomethyl bụ ihe kwụsiri ike na kemịkalụ nke na-adịghị erere ma ọ bụ nweta mmeghachi omume kemịkal n'ụzọ dị mfe.

 

Jiri:

A na-ejikarị Dibromomethane eme ihe dị ka ihe mgbaze maka mmeghachi omume njikọ organic, igbari ma ọ bụ wepụ lipids, resins na ihe ndị ọzọ na-emepụta ihe.

A na-ejikwa Dibromomethane dị ka akụrụngwa maka nkwadebe nke ogige ndị ọzọ, ma nwee ngwa na ụfọdụ usoro mmepụta ihe.

 

Usoro:

A na-akwadokarị Dibromomethane site n'imeghachi methane na bromine.

N'okpuru ọnọdụ mmeghachi omume, bromine nwere ike dochie otu ma ọ bụ karịa hydrogen atọm na methane ka ọ bụrụ dibromomethane.

 

Ozi nchekwa:

Dibromomethane na-egbu egbu, enwere ike ịmịnye ya site na ikuku ume, mmetụ akpụkpọ ahụ, ma ọ bụ iri nri. Ikpughe ogologo oge nwere ike inwe mmetụta ahụike dị njọ.
