Cov tshuaj tiv thaiv ntawm 2 - butene thiab bromine ua form 2 , 3-dibromobutane tsuas yog ib qho piv txwv ntawm qhov sib ntxiv cov tshuaj tiv thaiv ntawm alkenes thiab alkynes.
Tsis tas li ntawd, yuav ua li cas thaum ethene reacts nrog bromine?
Ethene reacts nrog kua bromine muab 1, 2-dibromoethane. Ethene thiab tshuaj tiv thaiv bromine kuj muab ib tug symmetrical alkyl halide compound. Ob bromine Cov atoms txuas nrog rau ob lub atoms ntawm cov pa roj carbon ethene molecule. Qhov no tshuaj tiv thaiv tuaj yeem ua tau ntawm chav tsev kub lossis qis dua qhov kub ntawm chav tsev.
Qhov thib ob, puas yog br2 ntxiv syn lossis anti? Nqe lus piav qhia: Kev kho ntawm alkenes nrog bromine ( Br2 ) muab vicinal dibromides (1, 2-dibromides). Lus Cim: Cov bromines ntxiv mus rau opposite ntsej muag ntawm ob daim ntawv cog lus ( tiv thaiv ntxiv”). Qee lub sij hawm cov kuab tshuaj tau hais hauv cov tshuaj tiv thaiv no - ib qho hnyav hnyav yog carbon tetrachloride (CCl4).
Hais txog qhov no, yuav ua li cas thaum br2 reacts nrog alkene?
Alkenes teb hauv qhov txias nrog cov kua ntshiab bromine , los yog nrog ib tug daws ntawm bromine nyob rau hauv cov organic hnyav xws li tetrachloromethane. Ob daim ntawv cog lus tawg, thiab a bromine atom ua txuas rau txhua cov pa roj carbon. Cov bromine poob nws cov xim liab-xim av kom muab cov kua tsis muaj xim.
Vim li cas cov xim ploj thaum bromine reacts nrog alkene?
Thaum twg bromine reacts nrog alkene , liab tsaus xim ntawm Br2 ploj sai li cov atoms ntawm bromine tsim daim ntawv cog lus nrog cov pa roj carbon atoms hauv ob daim ntawv cog lus. Yog tias xim ploj sai heev, peb paub tias cov compound muaj ib qhov chaw tsis txaus.

Thaum cov roj nitrogen reacts nrog hydrogen gas ammonia gas tsim?
Nyob rau hauv lub thawv muab, ammonia yog tsim los ntawm kev sib xyaw ntawm rau moles ntawm nitrogen gas thiab rau moles ntawm hydrogen gas. Hauv cov tshuaj tiv thaiv no, plaub moles ntawm ammonia yog tsim los ntawm kev noj ob moles ntawm nitrogen gas
Yuav ua li cas tshwm sim thaum bromine reacts nrog ib tug alkene?
Alkenes hnov mob hauv qhov txias nrog cov kua ntshiab bromine, lossis nrog kev daws ntawm bromine hauv cov kuab tshuaj organic xws li tetrachloromethane. Qhov ob daim ntawv cog lus tawg, thiab ib qho bromine atom ua txuas rau txhua cov pa roj carbon. Cov bromine poob nws cov xim liab-xim av kom muab cov kua tsis muaj xim
Thaum koj kub calcium carbonate ib qho khoom dawb nrog cov mis CaCO3 nws tawg los ua cov khoom calcium oxide CaO thiab carbon dioxide gas co2?
Thaum tshav kub kub tshaj 840 ° C, calcium carbonate decomposes, tso cov pa roj carbon dioxide thiab tawm hauv qab calcium oxide - cov khoom dawb. Calcium oxide hu ua txiv qaub thiab yog ib qho ntawm 10 cov tshuaj uas tsim tawm txhua xyoo los ntawm thermal decomposition ntawm limestone
Cov tshuaj tiv thaiv hu ua dab tsi thaum cov kua qaub reacts nrog lub hauv paus?
Cov tshuaj tiv thaiv ntawm cov kua qaub nrog lub hauv paus yog hu ua cov tshuaj tiv thaiv neutralization. Cov khoom ntawm cov tshuaj tiv thaiv no yog ntsev thiab dej. Piv txwv li, cov tshuaj tiv thaiv ntawm hydrochloric acid, HCl, nrog sodium hydroxide, NaOH, cov kev daws teeb meem tsim cov tshuaj sodium chloride, NaCl, thiab qee cov dej molecules ntxiv
Cov roj twg yog tsim thaum dilute hydrochloric acid reacts nrog magnesium carbonate?
