Carbon dioxide yog linear, thaum sulfur dioxide yog khoov (V-puab). Nyob rau hauv cov pa roj carbon dioxide, ob ob daim ntawv cog lus sim kom deb li deb li sai tau, thiab yog li cov molecule yog linear. … Yuav kom txo qis kev tawm tsam, ob daim ntawv cog lus thiab ob leeg ib leeg tau sib nrug deb npaum li qhov ua tau, thiab yog li cov molecule yog khoov.
Vim li cas SO2 khoov tab sis CO2 tsis yog?
Nyob hauv CO2 tsis muaj ib khub ntawm carbon atom, tab sis nyob rau hauv SO2 sulfur muaj ib leeg ib khub thiab repulsion ntawm daim ntawv cog lus thiab qiv nyiajyog li khoov rau hauv cov duab.
Vim li cas CO2 thiaj li muaj cov kab tawm?
Cov pa roj carbon nyob rau hauv qhov chaw vim nws muaj qis electronegativityYog tias peb tsuas tsim ib daim ntawv cog lus los ntawm C-O, cov pa roj carbon tsis tsim cov octet ruaj khov ntawm electrons yog li peb yuav tsum tau los ntawm ob npaug. daim ntawv cog lus. O=C=O. Tsuas muaj kev sib koom ua ke ntawm electrons nyob ib ncig ntawm cov pa roj carbon uas sib npaug sib npaug yog li cov molecule yog linear.
CO2 zoo li cas thiab vim li cas?
Tus qauv VSEPR thawj zaug rau CO2 molecule yog Tetrahedral Rau txhua daim ntawv cog lus ntau (ob npaug / triple daim ntawv cog lus), rho tawm ib qho hluav taws xob los ntawm tag nrho qhov kawg. Lub CO2 molecule muaj 2 ob daim ntawv cog lus kom rho tawm 2 electrons los ntawm tag nrho cov kawg. Yog li tag nrho tag nrho cov xov tooj ntawm electrons yuav tsum yog 2, qhov no yog lub cheeb tsam electron.
Puas CO2 puas muaj daim ntawv cog lus triple?
Qee lub molecules muaj ob lossis peb daim ntawv cog lus. Hom kev sib cog lus no tshwm sim thaum ntau tshaj ib khub ntawm cov hluav taws xob sib koom ntawm cov atoms kom ncav cuag lub plhaub sab nraud (ob npaug - 2 khub ntawm electrons, triple bond - 3 khub ntawm electrons). Ib qho piv txwv yog carbon dioxide. Qhov no tuaj yeem sawv cev ua 0=C=0.
