Dab tsi yogNtiv Nplhaib
Lub nplhaib conjugated yog ib lub kollic molecule ua los ntawm atoms (feem ntau carbon) sib txuas nrog kev sib txuas nrog cov tshuab hluav taws xob zoo li no Π tshuab hluav taws xob tau cuam tshuam rau tag nrho lub nplhaib. Qhov no txhais tau tias lub tshuab hluav taws xob Π nyob ib ncig ntawm tag nrho lub nplhaib, ntau dua li ua ib puag ncig ntawm ob qho kev sib tw uas nyob ib sab.
Lub delocalization ntawm tshuab hluav taws xob hauv lub nplhaib sib xyaw nrog ntau yam khoom tseem ceeb, suav nrog kev ruaj khov ntau thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Piv txwv li, ntau lub conjugated rings yog muaj peev xwm nqus tau lub teeb nyob rau hauv cov kev pom, thiab lawv tuaj yeem ua hluav taws xob vim yog lub sijhawm mus ncig ntawm lawv cov tshuab hluav taws xob delocalized.
Qee cov piv txwv ntawm cov nplhaib sib txuas suav nrog benzene, pyridine, thiab furan. Cov lwg me me no tseem ceeb hauv ntau qhov ntawm chemistry, suav nrog cov synthes organic, cov ntaub ntawv kawm txuj ci, thiab biochemistry.
