Carbon monoxide yog ib tug hetero nuclear diatomic molecule. Nws yog a polar covalent molecule raws li electronegativity sib txawv ntawm oxygen thiab carbon yog ntau dua 0.4, li no, daim ntawv a polar covalent bond.

Ua raws li qhov no, hom ntawv cog lus twg yog CO?

Cov pa roj carbon monoxide muaj ib tug carbon atom thiab ib tug oxygen atom, txuas los ntawm ib tug triple daim ntawv cog lus uas muaj ob covalent daim ntawv cog lus as well as ib dative covalent daim ntawv cog lus . Nws yog qhov yooj yim tshaj plaws oxocarbon thiab isoelectronic nrog cov cyanide anion, nitrosonium cation thiab molecular nitrogen.

Ib yam li ntawd, qhov molecular polarity ntawm CO yog dab tsi thiab vim li cas? Oxygen muaj cov electronegativity ntau dua li cov pa roj carbon, yog li nws yuav rub cov electrons hla, ua rau cov pa oxygen ib feem tsis zoo. Tsis zoo li cov pa roj carbon dioxide, tsis muaj oxygen atom thib ob los tiv thaiv kev rub tawm. Yog li ntawd, carbon monoxide yog polar.

Kuj nug, yog co polar lossis nonpolar lossis ionic?

Cov pa roj carbon dioxide ( CO 2) muaj ob polar C = O. bonds, tab sis lub geometry ntawm CO 2 yog linear thiaj li hais tias ob daim ntawv cog lus dipole lub sij hawm tshem tawm thiab tsis muaj net molecular dipole lub sij hawm; molecule yog tsis muaj polar.

Puas yog cov pa roj carbon thiab sulfur yog cov khoom sib txuas?

Qhov C-O daim ntawv cog lus yog considerably polar . Txawm hais tias C thiab S muaj qhov zoo sib xws ntawm electronegativity, S yog me ntsis ntau electronegative tshaj C, thiab yog li C-S daim ntawv cog lus yog me ntsis xwb polar . Vim tias oxygen yog electronegative ntau dua leej faj , oxygen kawg ntawm lub molecule yog qhov tsis zoo kawg.
