Txhua orbital muaj ob lub electrons. π 4 thiab π 5 yog degenerate antibonding orbitals nrog ob nodes ntawm txoj cai kaum rau ib leeg. p6 yog antibonding orbital nrog peb nodes.

Tom qab ntawd, muaj pes tsawg leeg ntawm sigma antibonding orbital muaj?

Cov anti-bonding sigma p orbitals muaj peb lub dav hlau nodal. Cov sigma p kev sib raug zoo orbital yog lub zog qis tshaj plaws orbital uas txhais tau tias nws yuav muaj xoom nodes . Tom qab ntawd muaj qhov sib txuas ntawm pi orbitals (1 node ), pib anti-bonding orbitals (2 nodes ) thiab thaum kawg lub anti-bonding sigma p orbital uas muaj peb nodes.

Muaj pes tsawg leeg nyob rau hauv lub siab tshaj plaws lub zog molecular orbital? Cov lub zog siab tshaj theem ("penthouse" ntawm peb lub tsev) muaj (n–1) nodes . Peb pom tias butadiene (n=4) lub lub zog siab tshaj qib muaj peb nodes nruab nrab ntawm orbitals (cim ntawm no nrog cov kab liab).

Ib yam li ntawd, cov nodes hauv molecular orbitals yog dab tsi?

Orbital ntawm ( node ): Ib qho taw tes lossis dav hlau ofzero electron ceev hauv ib orbital . Ib txwm ciam teb los ntawm ob lossis ntau dua orbital lobes. Cov π orbital ntawm ethylenehas ob orbital lobes (ib qho qhia hauv liab thiab lwm yam inblue), thiab ib qho orbital ntawm (lub dav hlau uas muaj theats).

Muaj pes tsawg lub dav hlau nodal nyob hauv 2p orbital?

Txhua 2 p oib muaj ob lub lobes. Muaj ib tug planarnode ib txwm rau lub axis ntawm lub orbital (yog li ntawd 2 ib p x orbital muaj yz nodal dav hlau , piv txwv).
