In chemistry, a cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.In inorganic cyanides, the cyanide group is present as the cyanide anion −C≡N. This anion is extremely poisonous. Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts.
Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon. For example, in acetonitrile (CH3−C≡N), the cyanide group is bonded to methyl (−CH3). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic.
Picha: Sararat Rangsiwuthaporn
Sararat Rangsiwuthaporn alikamatwa wiki iliyopita kwa tuhuma za kumuua Rafiki yake Siriporn Kanwong ambapo alibainika kuwaua 12 wengine kwa sumu hiyo
Polisi inachunguza vifo hivyo ambapo wahasiriwa wote walikula au kunywa na Sararat kabla ya kifo chao
Inaelezwa...
Mihogo huwa ina sumu inayoitwa cyanide. Sumu hii hupatikana kwa wingi sana kwenye mihogo michungu. Lakini pia ipo kwa kiasi fulani kwenye mihogo ile mitamu. Sumu hii ni kali sana, ikizidi inaua mara moja. Ndiyo hata wqle majasusi unaona wnajiua kwa kutumia cyanide iwapo wamekamatwa na hawataki...
