Dab tsi yog o-Xylene (ortho-xylene)?
o-Xylene (ortho-xylene) yog ib qho muaj ntxhiab hydrocarbon nrog cov mis molecular C8H10. Nws zoo nkaus li tsis muaj xim, me ntsis oily, flammable kua thiab yog ib qho ntawm peb isomers ntawm xylene. Nws cov qauv tseem ceeb yog lub nplhaib benzene nrog ob pawg methyl txuas mus rau qhov nyob ib sab (1,2-txoj hauj lwm) carbon atoms. Nws feem ntau yog siv los tsim phthalic anhydride, cov khoom siv tseem ceeb rau cov yas, xim, thiab txheej.
Dab tsi yog cov qauv molecular thiab cov qauv ntawm o-xylene
Molecular Formula: C8H10(tseem sau li C6H4(CH3)2).
Qauv
- Benzene Ring Core: Cov molecule yog tsim nyob ib ncig ntawm ib tug rau -carbon aromatic nplhaib, uas ua rau nws ruaj khov, cyclic qauv.
- Cov Pab Pawg Methyl uas nyob ib sab: Daim ntawv lo "ortho" qhia tias ob pawg methyl (−CH 3) txuas rau ib sab ntawm lub nplhaib benzene (txoj hauj lwm 1 thiab 2). Qhov no txawv ntawm meta-xylene (paub ntawm 1,3) thiab para-xylene (paub ntawm 1,4).
- SMILES Structure: CC1=C(C)C=CC=C1
