Ob leeg [Acetone] thiab [H+] yog qhov kev txiav txim thawj zaug, ua rau tag nrho qhov kev txiav txim thib ob.

Yuav ua li cas yog qhov kev txiav txim ntawm iodination ntawm acetone?

Lub iodination ntawm acetone kuj catalyzed los ntawm hydrogen ions. Cov teebmeem ntawm qhov sib txawv ntawm qhov sib txawv ntawm acetone, iodine thiab hydrogen ions tau kawm ua ntej thiab nws tau pom tias cov tshuaj tiv thaiv yog xoom xaj nrog rau iodine.

Y Yam xaj dab tsi yog tus nqi ntawm iodination ntawm acetone nrog rau iodine?

Cov txiaj ntsig tau qhia tias cov tshuaj tiv thaiv 4 muaj qhov siab tshaj plaws thiab yog li qhov kev pom zoo uas yuav tsum tau siv rau lawv kom hnov mob ntawm tus nqi ntawd yuav yog 6.66×10-1 M ntawm acetone, 3.33 × 10-1 M ntawm HCl, 5.00 mL dej thiab 1.11 × 10-3M ntawm iodine. Qhov no txhua yam tshwm sim ntawm tus nqi ntawm 8.34 × 10 - 1

YYuav ua li cas yog lub tshuab ntawm iodination ntawm acetone?

Acetone iodination cov tshuaj tiv thaiv mechanism. Txij li thaum ketones yog cov hauv paus tsis muaj zog heev, qhov sib npaug ntawm thawj cov tshuaj tiv thaiv saum toj no tsis zoo rau kev tsim cov ion. Raws li cov xwm txheej no [Ion]=K[Ac][H+, qhov twg K yog qhov sib npaug tsis tu ncua rau qhov kev tawm tsam no.

Qhov kev txiav txim tag nrho ntawm cov tshuaj tiv thaiv no yog dab tsi?

Qhov kev txiav txim tag nrho ntawm cov tshuaj tiv thaiv yog pom los ntawm kev ntxiv rau tus neeg txiav txim. Piv txwv li, yog tias cov tshuaj tiv thaiv yog thawj qhov kev txiav txim siab ntawm ob qho tib si A thiab B (a=1 thiab b=1), qhov kev txiav txim tag nrho yog 2.
