propan - 2 - ol yog CH3-CH(OH)-CH3 yog li nws yuav muaj −COCH3 pawg thiab li no muab qhov zoo iodoform xeem.
Kuj paub yog, puas yog 2 propanol muab tshuaj iodoform?
Rau muab Iodoform kuaj , yuav tsum muaj CH3-C(OH) los yog CH3-C = O, uas yog methyl pawg ntawm lub davhlau ya nyob twg. 2 . Tab sis nyob rau hauv Propanol , muaj Ethyl pawg ntawm lub davhlau ya nyob twg, yog li nws ua tsis muab Iodoform xeem.
Kuj Paub, koj tuaj yeem sib txawv ntawm propanol thiab propan 2 ol li cas? Ethanol yog thawj cawv , nws yuav qhia turbidity ntawm kev sib xyaw nrog Lucas Reagent tsuas yog nyob rau nruab nrab cua sov. Propan - 2 - ol yog tus thib ob cawv , nws yuav qhia turbidity tom qab 5-10 min. nrog cov tshuaj tsis muaj cua sov.
Yog li ntawd, yog vim li cas 2 propanol muab qhov zoo iodoform kuaj?
(Ib qho aldehyde lossis ketone uas muaj pab pawg methyl uas nyob ib sab ntawm pab pawg carbonyl yuav muab qhov kev kuaj pom zoo .) 2 ) Muab tus qauv ntawm cov compounds uas ua tsis muab qhov kuaj pom zoo Iodoform thiab muaj cov yam ntxwv hauv qab no. 1- Propanol ua tsis muab qhov kev ntsuam xyuas Iodoform zoo.
Yam cawv twg tsis muab iodoform kuaj?
Ethanol tsuas yog thawj cawv los muab cov tshuaj tiv thaiv triiodomethane (iodoform). Yog tias "R" yog pawg hydrocarbon, ces koj muaj cawv thib ob. Ntau cov cawv thib ob muab cov tshuaj tiv thaiv no, tab sis cov uas ua txhua tus muaj methyl pawg txuas nrog cov pa roj carbon nrog -OH pawg.
