Peb paub tias ob leeg yog tuav nyob rau hauv ib qho hybridized sp2 orbital vim tias ob daim ntawv cog lus txuas nrog nitrogen muaj pi daim ntawv cog lus pi nyiaj hauv chemistry, pi bonds (π bonds) yog covalent chemical bonds qhov twg ob lub lobes ntawm lub orbital ntawm ib lub atom sib tshooj ob lub lobes ntawm lub orbital ntawm lwm lub atomthiab qhov sib tshooj no tshwm sim tom qab. … Pi daim ntawv cog lus tuaj yeem tsim ua ob thiab peb daim ntawv cog lus tab sis tsis tsim hauv ib daim ntawv cog lus feem ntau. https://en.wikipedia.org › wiki › Pi_bond
Pi daim ntawv cog lus - Wikipedia
(i.e. lub unhybridized p orbital p orbital Keeb kwm. Lub sij hawm "orbital" yog coined los ntawm Robert Mulliken nyob rau hauv 1932 raws li ib tug abbreviation rau ib-electron orbital yoj muaj nuj nqi. //en.wikipedia.org › wiki › Atomic_orbital
Atomic orbital - Wikipedia
) uas yuav tsum muaj ib khub ntawm electrons siv los ua ob daim ntawv cog lus.
khub ib leeg nyob qhov twg?
Lone khub muaj nyob rau hauv lub plhaub sab nraud ntawm cov atoms. Lawv tuaj yeem raug txheeb xyuas los ntawm kev siv tus qauv Lewis. Cov khub hluav taws xob yog li ntawd suav tias yog ib leeg khub yog tias ob lub tshuab hluav taws xob sib txuas tab sis tsis siv hauv kev sib txuas tshuaj.
khub niam txiv mus nyob qhov twg?
Quick shortcut: Ib khub adjacent rau pi-bonds (thiab pi-systems) nyiam nyob rau hauv unhybridized p orbitals, es tsis nyob rau hauv hybridized sp orbitals. Yog li thaum lub nitrogen uas koj yuav xav tias yuav yog trigonal pyramidal sp3yog nyob ib sab ntawm daim ntawv cog lus pi, nws cov hybridization yog tiag tiag sp2 (trigonal planar).
Koj puas suav nrog ib leeg khub hauv hybridization?
Lone khub yog electron pawg uas suav rau hybridization. Cov khub ib leeg suav ua ib pawg electron rau tag nrho hybridization. Oxygen muaj ob leeg ib leeg. Nrog rau ob lub atoms sib txuas, hydrogen's, lub hauv paus atom muaj tag nrho ntawm plaub pawg electron, muab lub hauv paus atom ib sp3 hybridization.
Sp3 puas muaj ib khub?
Yog ib leeg electron khub muaj nyob rau ntawm lub hauv paus atom, lawv tuaj yeem nyob ntawm ib lossis ntau dua ntawm sp3 orbitals . Piv txwv li, hauv ammonia molecule, plaub ntawm sp3 hybrid orbitals ntawm cov nitrogen muaj ob qhov seem sab nrauv-plhaub electrons, uas tsim ib qho tsis sib koom ua ke.
