Carbon thiab oxygen ua ke muaj tag nrho ntawm 10 electrons hauv lub plhaub valence. Ua raws li txoj cai octet rau ob qho tib si carbon thiab oxygen, ob lub atoms tsim ib daim ntawv cog lus triple, nrog rau cov khoom siv hluav taws xob hauv peb kev sib txuas molecular orbitals, es tsis yog ob daim ntawv cog lus ib txwm pom hauv cov organic carbonyl compounds.
Vim li cas cov pa roj carbon thiab oxygen tuaj yeem ua rau peb daim ntawv cog lus tsim carbon monoxide?
Carbon monoxide muaj peb npaug carbon-oxygen daim ntawv cog lus. Peb tau hais tias ib qho ntawm cov ntawv cog lus no yog kev sib koom tes covalent daim ntawv cog lus. Nyob rau hauv covalent daim ntawv cog lus, ib khub ntawm electrons yog sib koom ntawm ob nonmetal atoms. … Cov pa roj carbon thiab cov pa oxygen ob leeg pub dawb valence electron los ua ib daim ntawv cog lus tsis tu ncua.
Yuav ua li cas daim ntawv cog lus yog carbon monoxide?
Cov pa roj carbon monoxide molecule tau raug sawv cev los ntawm triple covalent daim ntawv cog lus ntawm cov pa roj carbon thiab oxygen atoms. Ib qho ntawm cov ntawv cog lus yog kev sib koom ua ke covalent daim ntawv cog lus, ib daim ntawv cog lus uas ib qho ntawm cov atoms txhawb nqa ob qho tib si ntawm cov hluav taws xob hauv cov khub sib koom.
Puas yog carbon dioxide triple bonded?
Rau qhov molecule CO2 lub hauv paus atom yog carbon (C). … Thawj VSEPR puab rau CO2 molecule yog Tetrahedral. Rau txhua daim ntawv cog lus ntau (ob npaug / tripledaim ntawv cog lus), rho tawm ib qho hluav taws xob los ntawm tag nrho cov kawg. Lub CO2 molecule muaj 2 ob daim ntawv cog lus kom rho tawm 2 electrons los ntawm tag nrho cov kawg.
Vim li cas CO2 tsis muaj daim ntawv cog lus triple?
Txoj cai octet yuav dhau mus rau P, S, Cl, Br, lossis I. Kauj Ruam 6. Yog tias lub hauv paus atom tsis muaj octet, tsim ob lossis triple daim ntawv cog lus los ntawm kev txav hluav taws xob los ntawm ib lossis ntau qhov peripheral atoms rau ua tiav octet… Rau CO2, carbon yog qhov tsawg dua electronegative atom yog li nws yuav tsum yog lub hauv paus atom.
