Puas yog acetone thiab acetaldehyde tib yam?
Acetone yog tus tswv cuab tsawg tshaj plaws ntawm pawg ketone, qhov acetaldehyde yog tus tswv cuab tsawg tshaj plaws ntawm pawg aldehyde. Qhov sib txawv tseem ceeb ntawm Acetaldehyde thiab Acetone yog cov pa roj carbon atoms hauv cov qauv; acetone muaj peb Carbon atoms, tab sis acetaldehyde tsuas muaj ob carbon atoms.
Koj puas yuav paub qhov txawv ntawm formaldehyde thiab acetaldehyde?
Formaldehyde thiab acetaldehyde tuaj yeem sib txawv los ntawm iodoform test. - Methyl ketones hnov mob nrog iodine thiab poov tshuaj hydroxide kom daj precipitate. - Acetaldehyde reacts nrog iodine thiab KOH muab sodium ntsev ntawm carboxylic acid.
Puas yog acetaldehyde muab iodoform kuaj?
Iodoform yog cov tshuaj sib xyaw triiodomethane nrog cov tshuaj formula CHI3. … Los ntawm cov txheej txheem tshuaj tiv thaiv saum toj no, nws pom tseeb tias muaj cov tshuaj methyl (CH3) yog qhov yuav tsum tau muab rau kev kuaj iodoform zoo. Li no ethanal lossis acetaldehyde (CH3CHO) yog tib qho kev sib xyaw ntawm cov kev xaiv uas muab cov tshuaj tiv thaiv iodoform.
