Here kotuari Nonpolar - te here matū i hanga e te taua ngota

here kotuari Nonpolar e pā ana ki te kuware here matū. Kei te hanga e te reira e te takirua irahiko noa. E 2 ngā momo o rōpū kotuari e rerekē tikanga hanganga. Fakakaukau ki tona mātauranga me te ako atu e pā ana ki te mea te mea te nuinga o te here kore-neke. Kei te maha i hanga te reira i roto i ngā matū ohie - nonmetals, Heoi, ka taea e puta i roto i te pūhui i hanga e te ngota rerekē, me te kia āhei rite te uara electronegativity o matūriki. Hei tauira, PH3 rawa eo (P) = EA (H) = 2.2.

A feruri i, rite te here kotuari kore-neke i hanga te. I roto i te ngota hauwai kotahi anake irahiko, kia kore he oti tona anga irahiko, kāore reira ara 1. Ko te pāhekoheko o ngota hauwai timata ki te whakatata tahi i te tahi e tika ana ki te ope o te attraction o te karihi me ngā irahiko, i nga kapua irahiko wāhanga inaki. I roto i tenei doublet e hanga e, e no ki e rua matūriki timatanga. I roto i te wahi i reira inakitia nga kapua irahiko tahi e te tahi, i reira he he kiato irahiko nui haere, E rata ana te karihi ngota, reira whakarato ratou ki te rāpoi ngota pūhui mārō. tuhituhia schematically Irahiko here nonpolar e whai ake:

· + H · H - H: H H ranei - N.

Here, denoted te irahiko unpaired o te paparanga waho e tetahi wāhi, me te tapeke irahiko takirua o rua ira -: ranei pīhono.

Mai i te runga ake e taea te kite i te reira e te wāhi o te īnaki o kapua irahiko kei symmetrically ki te faatura ki te ngota e rua. I roto i te tikanga rite ki te hanga i te here kotuari kore-neke i roto i te take o ngā rāpoi ngota ohie, matū he maha nui o irahiko.

Mai te mea angamaheni mo te nuinga-konganuku kore tenei hononga, ka taea e koe whakaturia he tauira, e pā ana ki o ratou tinana āhuatanga. Matū ki te rōpū kotuari apolar kia totoka (silicon, he whanariki), haurehu (hauwai me te hāora) me te wai (bromo anake). Ki te titiro koe tata ki te ma rāpoi ssy haurehu waihā me te wai whakarewa-kore, kua kite te reira i taua ki te whakanui ake maha Mr faarahi te rewa, me te pāmahana kohua. Ki te nonmetals totoka taua e kore e puta. Ko te mea, ko te e enei matū ohie i hanganga ngota-tioata e tahi kaha here kotuari nonpolar. Ko te kupu, ko te nui i te maha o taua hononga, te uaua te pūhui, hei tauira, taimana me te graphite.

He nui i roto i te tukanga ora o ngā kaiao rōpū Nonpolar, rite Ko reira nui kaha me atu eu, me te hauwai katote. I roto i te tikanga ki te wahi i taua hononga, kararehe te tipu e tika ana ki te whakapau moni nui o te pūngao ranei, na te huarahi o te whakangaromanga o whākōkī tango te wahi kaha.

here kotuari Nonpolar - he here i hanga e nga ngota taua rerekē ranei o matūriki pūmotu o te pūhui matatini he rite uara o electronegativity. Ko te kupu rite mau i te ngota takirua irahiko noa (doublet).
