Furan thiab pyrrole muaj heterocyclic tsib-ntiv nplhaib, nyob rau hauv uas lub heteroatom muaj tsawg kawg yog ib khub ntawm non-bonding valence plhaub electrons. Los ntawm hybridizing no heteroatom mus rau ib lub xeev sp2, ib tug p-orbital nyob los ntawm ib tug khub ntawm electrons thiab oriented parallel mus rau cov pa roj carbon p-orbitals yog tsim.
Qhov heteroatom muaj nyob hauv pyrrole?
Pyrrole, furan, thiab thiophene molecules txhua tus muaj tsib lub nplhaib, muaj li plaub lub atom ntawm carbon thiab ib atom ntawm nitrogen, oxygen, los yog sulfur, raws li. Pyridine thiab pyrrole yog ob qho tib si nitrogen heterocycles -lawv cov molecules muaj nitrogen atoms nrog rau cov pa roj carbon atom hauv cov nplhaib.
Qhov heteroatom muaj nyob hauv pyrrole 8?
Pyrrole yog 5-tus tswvcuab uas muaj ntxhiab heterocycle, zoo li furanthiab thiophene. Tsis zoo li furan thiab thiophene, nws muaj dipole uas qhov kawg zoo nyob rau sab ntawm heteroatom, nrog lub sijhawm dipole ntawm 1.58 D.
heteroatom cuam tshuam li cas rau chemistry ntawm pyridine?
