Nitronium thiab nitrosonium ions yog inorganic ions uas muaj nitrogen thiab oxygen atoms. Ob qho ions no tshwm sim hauv cov tshuaj sib xyaw ua cations.
Nitronium yog dab tsi?
Nitronium ion yog ib qho cation uas muaj cov tshuaj formula NO2+. Peb tuaj yeem muab nws lub npe hu ua onium ion vim nws cov tetravalent nitrogen atom thiab +1 hluav taws xob uas zoo ib yam li ammonium ion. Qhov cation no yog tsim thaum lub electron tshem tawm ntawm paramagnetic nitrogen dioxide molecule los yog los ntawm protonation ntawm nitric acid.
Daim duab 01: Cov Qauv Tshuaj ntawm Nitronium Ion
Feem ntau, nitronium ion ruaj khov txaus kom muaj nyob rau hauv ib txwm muaj. Txawm li cas los xij, qhov no ion feem ntau yog reactive thiab muaj txiaj ntsig zoo li electrophile rau nitration ntawm lwm yam tshuaj. Rau lub hom phiaj no, no ion yog generated nyob rau hauv situ los ntawm kev sib xyaw concentrated sulfuric acid thiab concentrated nitric acid.
Peb tuaj yeem pom tias nitronium ion yog isoelectronic nrog carbon dioxide thiab nitrous oxide, thiab lawv muaj tib lub qauv kab thiab daim ntawv cog lus ntawm 180 degrees. Yog li ntawd, cov ion no muaj qhov zoo sib xws ntawm kev vibrational rau carbon dioxide.
Muaj qee cov ntsev ntawm nitronium ion qhov twg cov anions tsis muaj zog nucleophilic. Piv txwv xws li nitronium perchlorate (NO2+ClO4–), nitronium tetrafluoroborate (NO2+BF4-), nitronium hexafluorophosphate (NO2+PF6–), nitronium hexafluoroarsenate (NO2+AsF6– ), thiab nitronium hexafluoroantimonate (NO2+SbF6 -).
Nitrosonium yog dab tsi?
Nitrosonium yog ib qho cation uas muaj cov tshuaj NO +. Cov cation no muaj cov nitrogen atom sib txuas rau cov pa oxygen atom los ntawm triple daim ntawv cog lus. Yog li ntawd, daim ntawv cog lus ntawm cov molecule no yog 3. Txawm li cas los xij, ib qho oxygen atom tuaj yeem muaj ob daim ntawv cog lus tshuaj raws li nws cov khoom siv hluav taws xob; Yog li ntawd, lwm yam tshuaj lom neeg daim ntawv cog lus yog ib qho kev sib koom ua ke. Yog li ntawd, tag nrho cov hom diatomic bears ib tug zoo nqi. Qhov no tshwm sim raws li nitric oxide nrog ib tug electron tshem tawm.
Daim duab 02: Cov qauv tshuaj ntawm Nitrosonium Ion
Cov cation no yog isoelectronic nrog carbon monoxide (CO), cyanide anion (CN-), thiab nitrogen molecule (N2). Peb tuaj yeem tau txais nitrosonium ion yooj yim los ntawm protonation ntawm nitrous acid. Nws yooj yim reacts nrog dej, tsim nitrous acid. Yog li ntawd, peb yuav tsum tiv thaiv no ion los ntawm dej los yog huab cua noo. Thaum no ion reacts nrog lub hauv paus, nws muab nitrile tebchaw. Tsis tas li ntawd, nitrosonium ion tuaj yeem hnov mob nrog aryl amines ua tus neeg sawv cev diazotizing. Nitrosonium ion tuaj yeem ua lub zog oxidizing zoo ib yam.
Nitrosyl yog dab tsi?
Lub sij hawm nitrosyl yog siv rau lub npe nitric oxide ligand nyob rau hauv cov hlau complexes. Cov nitric oxide ligand yog sib koom ua ke rau lub hauv paus hloov pauv hlau los ntawm kev sib koom ua ke. Cov hlau complexes uas muaj NO ligand (nitric oxide) yeej muaj NO + cation uas yog hu ua nitrosyl cation (cov cation derived los ntawm nitrosyl ligand).
Daim duab 03: Kev Hloov Pauv Hlau Complex uas muaj Carbon Monoxide thiab Nitrosyl Ligands
Cov cation no yog isoelectronic nrog carbon monoxide. Yog li ntawd, cov qauv kev sib txuas ntawm carbon monoxide nrog cov hlau hloov pauv hauv carbonyl complexes zoo ib yam li cov nitrosyl complexes.
Dab tsi zoo sib xws ntawm Nitronium Nitrosonium thiab Nitrosyl?
- Tag nrho cov ions no muaj nitrogen thiab oxygen atoms.
- Cov no yog cov cations muaj tus nqi zoo.
- Lawv yog oxides ntawm nitrogen.
Qhov txawv ntawm Nitronium Nitrosonium thiab Nitrosyl yog dab tsi?
Nitronium thiab nitrosonium yog oxide ions ntawm nitrogen. Qhov sib txawv tseem ceeb ntawm nitronium nitrosonium thiab nitrosyl yog tias nitronium ion muaj ib qho nitrogen atom sib txuas rau ob lub pa oxygen thiab nitrosonium ion muaj ib lub nitrogen atom sib txuas rau ib lub atom oxygen thaum lub sij hawm nitrosyl siv thaum naming nitric oxide ligand hauv hlau complexes.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm nitronium nitrosonium thiab nitrosyl hauv daim ntawv.
Summary – Nitronium vs Nitrosonium vs Nitrosyl
Qhov sib txawv tseem ceeb ntawm nitronium nitrosonium thiab nitrosyl yog tias nitronium ion muaj ib lub nitrogen atom sib txuas rau ob lub atoms oxygen thiab nitrosonium ion muaj ib lub nitrogen atom sib txuas rau ib lub atom oxygen thaum lub sij hawm nitrosyl siv thaum naming nitric oxide ligand. nyob rau hauv cov hlau complexes.
