Qhov sib txawv tseem ceeb ntawm thiocyanate thiab isothiocyanate yog thiocyanate yog ib pab pawg ua haujlwm uas cov pawg alkyl lossis aryl txuas los ntawm cov sulfur atom whereas isothiocyanate yog qhov txuas isomer ntawm thiocyanate uas pawg alkyl lossis aryl txuas los ntawm cov nitrogen atom.
Thiocyanate thiab isothiocyanate yog pawg ua haujlwm uas muaj cov pa roj carbon, nitrogen, thiab sulfur atoms. Cov pab pawg ua haujlwm no muaj tib qhov sib txuas ntawm atoms. Ntawd yog, cov pa roj carbon atom nyob nruab nrab, thaum nitrogen thiab sulfur atoms txuas rau nws sab. Txawm li cas los xij, cov tshuaj sib txuas ntawm cov atoms no txawv ntawm ib leeg.
Thiocyanate yog dab tsi?
Thiocyanate yog ib qho anion uas muaj cov tshuaj formula -SCN– Nws ua haujlwm ua haujlwm hauv ntau cov organic tebchaw. Ntawm no, cov sulfur atom txuas nrog pawg alkyl lossis aryl, thaum lub nitrogen atom txuas tsuas yog rau cov pa roj carbon atom, uas yog nyob rau hauv nruab nrab ntawm pawg ua haujlwm. Yog li ntawd, sulfur atom muaj ib daim ntawv cog lus nrog cov pa roj carbon atom, whereas lub nitrogen atom muaj triple daim ntawv cog lus nrog carbon atom. Cov sulfur atom tsim lwm daim ntawv cog lus nrog pawg alkyl lossis aryl thaum tsim cov organic compound.
Daim duab 01: Kev Sib Piv Ntawm Thiocyanate thiab Isothiocyanate Functional Groups hauv Organic Compounds
Lub thiocyanate anion yog lub hauv paus conjugate ntawm thiocyanic acid. Cov piv txwv paub zoo dua rau cov tebchaw uas muaj cov anion no suav nrog cov tshuaj ionic, xws li potassium thiocyanate thiab sodium thiocyanate. Phenyl thiocyanate yog ib qho piv txwv ntawm cov organic compound uas muaj thiocyanate functional pawg. Cov pab pawg thiocyanate yog ib qho kev sib txuas isomer ntawm pawg isothiocyanate. Organic thiocyanate tebchaw yog ib qho tseem ceeb raws li lub tsev blocks hauv synthesizing sulfur-muaj cov organic tebchaw.
YIsothiocyanate yog dab tsi?
Isothiocyanate yog qhov txuas isomer ntawm thiocyanate ua haujlwm pab pawg. Yog li ntawd, pawg isothiocyanate kuj muaj carbon, nitrogen thiab sulfur atoms.
Daim duab 02: Cov Qauv Txheej Txheem ntawm Isothiocyanate Group
Txawm li cas los xij, tsis zoo li hauv thiocyanate, thaum tsim cov organic compound, pawg alkyl lossis aryl txuas mus rau pawg haujlwm no ntawm nitrogen atom. Ntawm no, peb tuaj yeem soj ntsuam ob daim ntawv cog lus ntawm carbon thiab nitrogen atoms. Kuj tseem muaj ob daim ntawv cog lus ntawm carbon thiab sulfur atoms qhov twg sulfur atom tsuas yog sib koom ua ke rau carbon atom.
Qhov txawv ntawm Thiocyanate thiab Isothiocyanate yog dab tsi?
Thiocyanate thiab isothiocyanate yog isomers; lawv yog linkage isomers vim lawv txuas nrog alkyl lossis aryl pawg ntawm cov ntsiab lus sib txawv. Qhov sib txawv tseem ceeb ntawm thiocyanate thiab isothiocyanate yog thiocyanate yog ib pab pawg ua haujlwm uas pawg alkyl lossis aryl tau txuas los ntawm leej faj atom, hos isothiocyanate yog qhov txuas isomer ntawm thiocyanate uas pawg alkyl lossis aryl tau txuas los ntawm nitrogen atom..
Ntxiv mus, muaj ib qho kev sib cog lus triple ntawm carbon thiab nitrogen atoms hauv pawg thiocyanate, thaum tsis muaj triple bonds ntawm carbon thiab nitrogen atoms hauv pawg isothiocyanate. Yog li ntawd, peb tuaj yeem soj ntsuam ib daim ntawv cog lus thiab triple daim ntawv cog lus ntawm atoms hauv pawg thiocyanate. Muaj ob daim ntawv cog lus ob npaug ntawm cov atoms ntawm pawg isothiocyanate. Tsis tas li ntawd, nyob rau hauv pawg thiocyanate, lub angular geometry tuaj yeem pom nyob ib puag ncig ntawm cov sulfur atom thaum, hauv pawg isothiocyanate, cov angular geometry muaj nyob ib ncig ntawm nitrogen atom.
Hauv qab infographic qhia txog qhov sib txawv ntawm thiocyanate thiab isothiocyanate.
Summary – Thiocyanate vs Isothiocyanate
Thiocyanate thiab isothiocyanate yog isomers; lawv yog linkage isomers vim lawv txuas nrog alkyl lossis aryl pawg ntawm cov ntsiab lus sib txawv. Qhov sib txawv tseem ceeb ntawm thiocyanate thiab isothiocyanate yog thiocyanate yog ib pab pawg ua haujlwm uas pawg alkyl lossis aryl txuas los ntawm cov sulfur atom, hos isothiocyanate yog qhov txuas isomer ntawm thiocyanate uas pawg alkyl lossis aryl txuas los ntawm nitrogen atom..
