Reactive txaus ntshai yog cov kev phom sij cuam tshuam nrog cov tshuaj tsis muaj tshuaj tiv thaiv hauv kev lag luam. Cov tshuaj tiv thaiv tsis tau tswj xyuas - xws li cov cua kub khiav thiab cov tshuaj lom neeg decompositions - tau ua lub luag haujlwm rau ntau qhov hluav taws kub, tawg, thiab tso pa tawm.
Nyob rau hauv txoj kev no, dab tsi yog qhov teeb meem tshwm sim los ntawm?
Cov ntaub ntawv reactive feem ntau suav hais tias yog cov ntaub ntawv uas tuaj yeem tsim kev puas tsuaj los ntawm lawv tus kheej thaum tshwm sim los ntawm tshav kub, siab, poob siab, kev sib txhuam, catalyst, lossis los ntawm kev sib cuag nrog huab cua lossis dej. Reactive kev sib cuam tshuam xav tau kev sib txuas ntawm ob lossis ntau cov ntaub ntawv los ua kom muaj kev phom sij los ntawm tshuaj tshuaj tiv thaiv.
Tsis tas li ntawd, dab tsi yog qee qhov piv txwv ntawm reactivity? Piv txwv ntawm chemical reactivity suav nrog kev sib xyaw ua ke los ua cov tshuaj thiab sib xyaw cov tshuaj lom lom nrog cov tshuaj nyob rau hauv ib puag ncig cuam tshuam.
Ib yam li ntawd, nws raug nug, uas yog ib qho piv txwv ntawm cov tshuaj reactive?
nrog dej. Txawm tias cov av noo hauv huab cua tuaj yeem ua rau muaj qhov tshwm sim yog tias nws los ntawm kev sib cuag nrog dej tshuaj reactive . Piv txwv ntawm dej cov tshuaj reactive muaj xws li sodium, titanium tetrachloride, boron triflouride, thiab acetic anhydride.
Dab tsi yog qhov piv txwv ntawm cov khoom siv phom sij txaus ntshai?
Rau piv txwv , sodium los yog potassium phosphide tso phosphine roj thaum lawv sib cuag dej. Alkali hlau cyanide ntsev, xws li sodium los yog potassium cyanide, maj mam tso cov pa roj hydrogen cyanide ntawm kev sib cuag nrog dej.
Pom zoo:
Yog vim li cas magnesium tsawg reactive dua sodium?
Sodium yog cov hlau electropositive ntau dua uas txhais tau hais tias nws "ntxub cov hluav taws xob ntau dua li magnesium yog li nws xav tau lub zog tsawg dua rau chuck electrons dua li magnesium. Cov no yog cov ntsiab lus tseem ceeb uas piav qhia vim li cas cov hlau sodium yog ntau dua li cov hlau magnesium
Dab tsi ntawm cov ntsiab lus yog qhov tsawg tshaj plaws reactive thiab vim li cas?
Noble gases yog qhov tsawg tshaj plaws reactive ntawm tag nrho cov ntsiab lus. Qhov ntawd yog vim lawv muaj yim valence electrons, uas ua rau lawv lub zog sab nraud. Qhov no yog qhov ruaj khov tshaj plaws ntawm cov khoom siv hluav taws xob, yog li noble gases tsis tshua muaj kev cuam tshuam nrog lwm cov ntsiab lus thiab cov khoom sib txuas
Dab tsi yog qhov reactive tshaj plaws rau sn2 cov tshuaj tiv thaiv?
SN2 cov tshuaj tiv thaiv yog nyiam los ntawm qhov tsawg kawg nkaus sterric hindrance yog qhov feem ntau reactive tom qab conjugated alkyl halide qhov twg tus nqi yog ceev los ntawm ib tug conjugation nyob rau hauv lub xeev hloov
Kev siv lub zog reactive yog dab tsi?
Reactive zog yog siv los muab cov voltagelevels tsim nyog rau active zog ua hauj lwm pab tau.Reactive zog yog ib qho tseem ceeb rau txav active powerthrough lub kis tau tus mob thiab tis system rau cov neeg muas zaub
Dab tsi alkaline ntiaj teb hlau yog feem ntau reactive nrog dej?
Cov hlau alkali (Li, Na, K, Rb, Cs, thiab Fr) yog cov hlau reactive tshaj plaws nyob rau hauv lub sij hawm lub sij hawm - lawv tag nrho cov hnov mob heev los yog txawm explosively nrog dej txias, uas ua rau lub displacement ntawm hydrogen
