Nonpolar covalent isibopho - isibopho chemical ezakhiwe athomu efanayo

Nonpolar covalent isibopho libhekisela elula amakhemikhali izibopho. Lakhiwa okuvame electron ngazimbili. Kukhona 2 izinhlobo zezinhlangano covalent zihlukile ukwakheka indlela. Cabanga imfundo yakhe futhi ufunde kabanzi mayelana nokuthi iyiphi ikakhulukazi kwebhondi non-polar. Kuvame kwakheka izinto ezilula - Nokho, nonmetals, kungavuka zezakhi ezakhiwe athomu ezahlukene, ne amalunga ukubaluleka electronegativity ka kuyizinhlayiyana alinganayo. Ngokwesibonelo, PH3 izidakamizwa EO (P) = EA (H) = 2.2.

Cabanga, njengoba akha non-polar covalent isibopho. Ngo -athomu ye-hydrogen -electron eyodwa kuphela, ngakho electron yayo igobolondo ayiphelele, awunazo ngisho 1. ukuxhumana ngama-athomu hydrogen uqale ukuzifinyelela nomunye ngenxa amabutho Luhambo ka nuclei futhi electron, kuyilapho ingxenye ezedlulayo electron amafu. Ngalesi doublet Kumiswa elingelakwaJuda izinhlayiya ezimbili aphansi. Endaweni lapho amafu electron baprofetha nomunye, kukhona anda electron ukuminyana, edonsela nuclei athomu, ngalokho lunikeze kubo okuqinile kwakwakhe-molecule. Covalent isibopho nonpolar schematically ebhaliwe ngale ndlela:

· + H · H - H: H noma H - N.

Lapha, i-electron ayibhangqiwe ungqimba yangaphandle luchazwa ngegama Ngesinye isikhathi, futhi inani electron pair of amachashazi amabili -: noma dash.

Ngokwalokhu okungenhla kuyabonakala ukuthi endaweni ukugqagqana of electron amafu elise afanako mayelana athomu amabili. Ngendlela efanayo ukwakha non-polar covalent isibopho uma molecule elula, izinto kokuba inombolo enkulu ama-electron.

Njengoba Lobu buhlobo ejwayelekile kakhulu ze-non-izinsimbi, ungasetha iphethini, ezihlobene zabo ezingokwenyama izakhiwo. Izinto nge apolar covalent inhlangano ingase ibe okuqinile (Silicon, isibabule), amagesi (i-hydrogen ne-oksijini) kanye ketshezi (kuphela bromo). Uma sihlole ma yamangqamuzana ssy gaseous ne liquid-non-metal, ubonakala ukuthi nge okwandisa Mr ngokuvamile kwandisa ukuncibilika lokushisa abilayo. Nge nonmetals okuqinile okunjalo ingekho. Into wukuthi lezi izinto ezilula abe-athomu-crystalline isakhiwo elisinika amandla nonpolar covalent isibopho. Ngakho, elikhulu inani uxhumano esinjalo, nzima enkompolo, isibonelo, idayimane kanye graphite.

inhlangano Nonpolar kubalulekile kule izinqubo zokuphila eziphilayo, njengoba ke Sinemandla futsi more uzinze, ne-hydrogen ion. Ukuze aphule izibopho ezinjalo, isilwane noma isitshalo kudingeka ukuba basebenzise esiningi namandla, ngakho lo mshini nolokubhujiswa enzyme ukuthatha ingxenye esebenzayo.

Nonpolar covalent isibopho - isibopho ezakhiwe athomu efanayo noma ezahlukene izinhlayiya aphansi kwakwakhe eziyinkimbinkimbi kokuba amanani alinganayo electronegativity. Ngakho ngokulinganayo ubambe athomu ezivamile electron bhangqa (doublet).
