Qhov sib txawv tseem ceeb ntawm benzenoid thiab tsis yog benzenoid tebchaw yog tias cov tshuaj benzenoid muaj tsawg kawg yog ib lub nplhaib benzene hauv cov molecule whereas non benzenoid compounds tsis muaj benzene rings.
Ib qho tshuaj tsw qab yog lub voj voog, cov qauv qauv nrog lub nplhaib ntawm cov ntawv cog lus resonance. Cov qauv no ruaj khov dua li cov qauv nplhaib ib txwm. Ob qho tib si benzenoid thiab tsis yog benzenoid tebchaw yog cov tshuaj tsw qab. Yog li ntawd, tag nrho cov tshuaj tsw qab tsis tas yuav yog benzenoid compounds.
YDab tsi yog Benzenoid
Benzenoid compounds yog cov molecules uas muaj tsawg kawg ib lub nplhaib benzene hauv nws cov qauv tshuaj. Lub nplhaib benzene yog ib lub voj voog uas muaj rau cov pa roj carbon atoms raws li cov tswv cuab ntawm lub nplhaib. Nws muaj peb daim ntawv cog lus pi (ob daim ntawv cog lus) thiab peb daim ntawv cog lus sib koom ua ke hauv ib qho qauv. Yog li ntawd, peb hu tus qauv no conjugated pi system.
Daim duab 01: Toluene - Benzenoid Compound
Vim tias cov molecule muaj ob daim ntawv cog lus vim lub nplhaib benzene, cov molecule yog ib qho tsis txaus ntseeg nrog kev ruaj ntseg ntxiv yog muab los ntawm conjugated pi system.
Dab tsi yog Benzenoid?
Non benzenoid compounds yog cov tshuaj tsw qab uas tsis muaj benzene rings hauv nws cov qauv tshuaj. Txawm hais tias lub nplhaib benzene tsis tuaj, cov molecules no muaj qhov sib txuas ntawm pi system. Lub nplhaib qauv ntawm cov tebchaw muaj nyob ib ncig ntawm 5-7 carbon atoms.
Daim duab 02: Azulene - Tsis yog Benzenoid Compound
Qhov aromatic tshwm sim vim muaj qhov sib txuas ntawm pi system. Qhov no conjugated pi system muab lub molecule nrog ntxiv stability. Qee qhov piv txwv xws li azulenes, Oxaazulanones, Pentafulvene, Tropones & Tropolones, thiab lwm yam.
Dab tsi zoo sib xws ntawm Benzenoid thiab Tsis yog Benzenoid?
- Ob leeg yog cov qauv kev sib tw
- Benzenoid thiab Tsis yog Benzenoid yog cov tshuaj tsw qab nrog cov kab ke sib txuas
- Ob leeg Benzenoid thiab Tsis yog Benzenoid nthuav tawm qhov kev ruaj ntseg ntxiv
Qhov txawv ntawm Benzenoid thiab Tsis yog Benzenoid yog dab tsi?
Txawm hais tias ob qho tib si benzenoid thiab tsis yog benzenoid compounds yog cov tshuaj tsw qab, lawv muaj ob peb qhov sib txawv ntawm lawv. Qhov txawv yog qhov muaj lub nplhaib benzene hauv ob lub tebchaw no. Nyob rau hauv benzene tebchaw muaj benzene rings tam sim no uas ua rau nws lub npe thaum lub nplhaib benzene tsis tuaj nyob rau hauv cov tsis yog benzene compounds. Cov txheej txheem sib txawv no yeej cuam tshuam rau cov khoom siv tshuaj lom neeg thiab kev ua haujlwm ntawm cov tebchaw.
Summary – Benzenoid vs Non Benzenoid
Ob qho tib si benzenoid thiab tsis yog benzenoid compounds yog cov qauv uas muaj ntxhiab uas muaj cov kab ke sib txuas. Yog li ntawd, ob qho tib si cov qauv no qhia ntxiv stability. Qhov txawv ntawm benzenoid thiab tsis yog benzenoid tebchaw yog tias benzene tebchaw muaj tsawg kawg yog ib lub nplhaib benzene nyob rau hauv lub molecule whereas tsis benzenoid tebchaw tsis muaj benzene rings.
