Qhov sib txawv tseem ceeb ntawm exocyclic thiab endocyclic ob daim ntawv cog lus yog tias ib qho carbon atom ntawm exocyclic ob daim ntawv cog lus yog nyob rau hauv lub nplhaib qauv thiab lwm cov pa roj carbon atom nyob sab nraum lub nplhaib qauv whereas ob carbon atoms ntawm endocyclic ob daim ntawv cog lus yog nyob rau hauv lub nplhaib qauv.
Exocyclic thiab endocyclic ob daim ntawv cog lus yog ib feem ntawm cov tshuaj sib txuas uas yog cov qauv voj voog lossis lub nplhaib. Ob daim ntawv cog lus no sib txawv ntawm ib leeg raws li qhov chaw ntawm ob lub atoms uas koom nrog kev tsim ntawm ob daim ntawv cog lus.
Dab tsi yog Exocyclic Double Bond?
Exocyclic ob daim ntawv cog lus yog covalent tshuaj bonds uas muaj ob lub pa roj carbon atoms sib koom ua ke ntawm sigma daim ntawv cog lus thiab daim ntawv cog lus pi. Hom ob daim ntawv cog lus no muaj ib qho ntawm ob lub pa roj carbon atom hauv lub nplhaib qauv. Peb tuaj yeem soj ntsuam exocyclic ob daim ntawv cog lus tsuas yog nyob rau hauv cov organic tsis sib xyaw ua ke (unsaturated compounds yog cov tshuaj sib txuas uas muaj ob daim ntawv cog lus lossis triple bonds). Tshwj xeeb, cov ntawv cog lus no tuaj yeem pom hauv alkenes.
Daim duab 01: Cov Qauv Tshuaj ntawm Methylenecyclohexane
Lub npe exocyclic hais txog qhov muaj ob daim ntawv cog lus sab nraud rau cov qauv cyclic. Tab sis ob daim ntawv cog lus no tseem txuas nrog cov qauv cyclic los ntawm ib qho ntawm ob qho kev sib koom ua ke carbon atoms. Nws yog ib qho tseem ceeb heev kom paub txog exocyclic ob daim ntawv cog lus tsim endocyclic ob daim ntawv cog lus thaum naming ib tug tshuaj compound siv IUPAC nomenclature txoj kev. Ib qho piv txwv ntawm cov tshuaj sib xyaw uas muaj cov exocyclic ob daim ntawv cog lus yog methylcyclohexane.
Dab tsi yog Endocyclic Double Bond?
Endocyclic ob daim ntawv cog lus yog covalent tshuaj bonds uas muaj ob lub pa roj carbon atoms sib koom ua ke ntawm sigma daim ntawv cog lus thiab ib daim ntawv cog lus pi (qhov muaj pes tsawg leeg ntawm ob daim ntawv cog lus). Covalent tshuaj bonds no muaj ob qho tib si carbon atoms ntawm ob daim ntawv cog lus nyob rau hauv lub nplhaib qauv. Hauv lwm lo lus, ob qho tib si carbon atoms ntawm endocyclic ob daim ntawv cog lus yog cov tswv cuab ntawm cov qauv cyclic.
Daim duab 02: Cov Qauv Tshuaj ntawm Cyclopentene
Ib qho piv txwv ntawm cov tshuaj sib xyaw uas muaj cov endocyclic ob daim ntawv cog lus yog cyclopentene. Cyclopentene muaj ib qho endocyclic ob daim ntawv cog lus txij li ob qho tib si ob qho tib si carbon atoms yog cov tswv cuab ntawm cov qauv cyclic. Nws yog ib qho tseem ceeb heev kom paub txog exocyclic ob daim ntawv cog lus tsim endocyclic ob daim ntawv cog lus thaum naming cov tshuaj siv tshuaj siv IUPAC nomenclature method.
Qhov txawv ntawm Exocyclic thiab Endocyclic Ob Daim Ntawv Pov Thawj yog dab tsi?
Exocyclic thiab endocyclic ob daim ntawv cog lus yog ib feem ntawm cov qauv cyclic uas txawv ntawm ib leeg raws li qhov chaw ntawm ob daim ntawv cog lus. Qhov sib txawv tseem ceeb ntawm exocyclic thiab endocyclic ob daim ntawv cog lus yog tias ib qho carbon atom ntawm exocyclic ob daim ntawv cog lus yog nyob rau hauv lub nplhaib qauv thiab lwm cov pa roj carbon atom nyob sab nraum lub nplhaib qauv whereas ob carbon atoms ntawm endocyclic ob daim ntawv cog lus nyob rau hauv lub nplhaib qauv.
Hauv qab infographic qhia txog qhov sib txawv ntawm exocyclic thiab endocyclic ob daim ntawv cog lus hauv daim ntawv tabular.
Summary – Exocyclic vs Endocyclic Ob Daim Ntawv Pov Thawj
Exocyclic thiab endocyclic ob daim ntawv cog lus yog ib feem ntawm cov qauv cyclic uas txawv ntawm ib leeg raws li qhov chaw ntawm ob daim ntawv cog lus. Qhov sib txawv tseem ceeb ntawm exocyclic thiab endocyclic ob daim ntawv cog lus yog tias ib qho carbon atom ntawm exocyclic ob daim ntawv cog lus yog nyob rau hauv lub nplhaib qauv thaum lwm cov pa roj carbon atom nyob sab nraum lub nplhaib qauv whereas ob carbon atoms ntawm endocyclic ob daim ntawv cog lus nyob rau hauv lub nplhaib qauv.
