Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab hloov cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv synthesis muab cov tshuaj lom neeg tshiab tsim los ntawm kev sib xyaw reactant, qhov kev hloov pauv tshuaj muab cov tshuaj sib xyaw uas tau muab los ntawm cov tshuaj uas twb muaj lawm.
Synthesis cov tshuaj tiv thaiv thiab hloov cov tshuaj tiv thaiv yog qhov tseem ceeb ntawm cov organic synthesis. Ob qho kev tawm tsam no tsim cov tshuaj lom neeg.
Dab tsi yog Kev Sib Tham Sib Tham?
A synthesis reaction is a type of chemical reaction in which two or more components together with each other to make a large compound. Cov tshuaj tiv thaiv synthesis yog qhov sib txawv ntawm cov tshuaj tiv thaiv dissociation. Peb tuaj yeem hu nws qhov kev sib xyaw ua ke ncaj qha ib yam nkaus vim tias nws koom nrog kev sib xyaw ua ke los ua ib qho kev sib xyaw tshiab. Tsis tas li ntawd, cov tshuaj reactants hauv cov tshuaj tiv thaiv no yog cov tshuaj lom neeg lossis cov tshuaj molecules. Cov khoom kawg ntawm cov tshuaj tiv thaiv synthesis yog ib qho kev sib txuas lossis ib qho nyuaj.
Piv txwv li, kev sib xyaw ntawm cov pa roj carbon dioxide thiab cov pa oxygen uas tsim cov dej molecules, kev sib xyaw ntawm carbon monoxide thiab oxygen uas tsim cov pa roj carbon dioxide, kev sib xyaw ntawm txhuas hlau thiab cov pa roj carbon monoxide uas tsim cov txhuas oxide, thiab lwm yam.
Daim duab 01: Tsim cov tshuaj lom neeg loj los ntawm kev sib xyaw ntawm Cov Me Me Reactant Molecules
Peb tuaj yeem lees paub cov tshuaj tiv thaiv synthesis los ntawm kev soj ntsuam cov khoom kawg; nws ib txwm yog ib qho compound. Nyob rau hauv cov kev tshwm sim no, tag nrho cov atoms tam sim no nyob rau hauv lub reactant molecules yuav tsum muaj nyob rau hauv cov khoom kawg. Ntxiv mus, thaum tsim daim ntawv cog lus, cov tshuaj tiv thaiv no tso tawm lub zog; yog li ntawd, lawv yog exothermic tshua.
Kev hloov pauv yog dab tsi?
Kev hloov pauv yog cov tshuaj tiv thaiv uas cov moieties ntawm molecules hloov cov moieties ntawm lwm cov molecules. Moiety yog ib feem ntawm lub molecule. Hauv cov tshuaj tiv thaiv no, cov moieties yog atoms, ions, lossis pawg ua haujlwm. Tsis tas li ntawd, cov tshuaj tiv thaiv no feem ntau tshwm sim los ntawm kev hloov cov pab pawg ua haujlwm ntawm cov molecule nrog rau lwm pab pawg ua haujlwm. Cov tshuaj tiv thaiv tshuaj no yog cov tshuaj tiv thaiv tseem ceeb heev hauv cov organic chemistry.
Daim duab 02: Hloov Cov Kev Sib Hloov Cov Txheej Txheem rau 2-Chlorobutane
Ntxiv mus, muaj ob hom kev hloov pauv hloov pauv raws li kev hloov pauv ntawm electrophilic thiab nucleophilic hloov pauv. Txawm li cas los xij, muaj lwm pawg ib yam nkaus; uas yog qhov kev hloov pauv radical.
Dab tsi yog qhov txawv ntawm Synthesis Reaction thiab Reaction Reaction?
Kev sib xyaw ua ke thiab hloov pauv cov tshuaj tiv thaiv yog cov tshuaj lom neeg tseem ceeb hauv cov tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab hloov cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv synthesis muab cov tshuaj lom neeg tshiab tsim los ntawm kev sib xyaw reactant, thaum cov tshuaj hloov pauv muab cov tshuaj sib xyaw uas tau muab los ntawm cov tshuaj uas twb muaj lawm. Ib qho piv txwv ntawm cov tshuaj tiv thaiv synthesis yog kev sib xyaw ntawm cov roj hydrogen thiab cov pa oxygen los tsim cov dej molecule thaum piv txwv rau kev hloov cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv electrophilic substation ntawm 2-chlorobutane.
Cov infographic hauv qab no qhia ntau qhov kev sib piv ntawm ob qho kev tawm tsam txhawm rau txhawm rau pom qhov sib txawv ntawm cov tshuaj tiv thaiv kev sib txuas thiab hloov cov tshuaj tiv thaiv.
Summary – Synthesis Reaction vs Hloov Reaction
Kev sib xyaw ua ke thiab hloov pauv cov tshuaj tiv thaiv yog cov tshuaj lom neeg tseem ceeb hauv cov tshuaj lom neeg. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab hloov cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv synthesis muab cov tshuaj lom neeg tshiab tsim los ntawm kev sib xyaw reactant, qhov kev hloov pauv tshuaj muab cov tshuaj sib xyaw uas tau muab los ntawm cov tshuaj uas twb muaj lawm..
