Raws li, muaj 3 I-atoms thiab 2 molecules ntawm iodoform ua feem ntau hnov mob, 6 nyiaj atoms siv rau hauv cov tshuaj tiv thaiv thiab lawv precipitate tawm 6 molecules ntawm AgI. Cov 2 carbon atoms tsim ib daim ntawv cog lus triple los tsim acetylene.

Ib yam li ib tug yuav nug, iodoform tsim li cas?

Thaum iodine thiab sodium hydroxide ntxiv rau ib qho chaw uas muaj methyl ketone los yog cawv thib ob nrog methyl pawg hauv alpha txoj hauj lwm, daj ntseg daj precipitate ntawm iodoform ua los yog triiodomethane tsim . Nws tuaj yeem siv los txheeb xyuas aldehydes lossis ketones.

Tsis tas li ntawd, qhov tsw ntawm iodoform yog dab tsi? Iodoform yog ib qho organioodine compound uas muaj cov qauv ntawm CHI3 thiab belongs rau tsev neeg ntawm cov organic halogen compounds. Nws yog crystalline daj daj yam khoom uas yog volatile nyob rau hauv cov xwm. Nws muaj qhov sib txawv thiab sib txawv tsw nrog sweetish tsw uas yog analogous rau chloroform.

Ib yam li ib tug yuav nug, puas yog iodoform muaj iodine hauv nws?

Iodoform yog ib qho organoiodine compound nrog cov mis CHI3 thiab tetrahedral molecular geometry. Iodoform yog soluble nyob rau hauv fatty acids thiab decomposes tso tawm iodine nyob rau hauv nascent xeev (96, 7% ntawm iodine ) thaum nyob rau hauv kev sib cuag nrog secretions los yog endodontic kab mob 2.

Yuav ua li cas tshwm sim thaum iodoform raug kho nrog nyiaj hlau?

Kev piav qhia: Thaum twg iodoform ua yog rhuab nrog nyiaj hmoov, ob leeg hnov qab muab acetylene lossis ethylene thiab nyiaj chloride ua ib yam khoom. Nyiaj yog ib qho kev txo qis uas txo cov chloroform rau hauv ethyl.
