Teraeagle skrev : Om en halogen binder till en kolatom så kommer den att dra elektrondensitet till sig. Då får kolatomen ett positivt oxidationstillstånd och blir mer "elektronälskande", dvs elektrofil. Elektrofil addition. keton + elektrofil → resonansstabiliseret katjon ; Wittigs reaktion. keton + fosfoniumylid → oxfosfeten .

Elektrofil addition

Additions reaktion. Vanligaste reaktionstypen; Dubbel- eller trippelbindning; Elektrofil och nukleofil addition. Be there for your students: A step by step guide plus Till vilket kol som vätet binder beror på reaktionen, och i detta fall är det en elektrofil addition så vätet kommer adderas till det kol med flest väten, Elektrofil addition (HCl/alken) Elektrofil addition (Br2/alken) Elektrofil aromatisk substitution (Br2/bensen) Nukleofil substitution (SN1, vatten /tert. halid) Nukleofil göra konformationsanalyser av substituerade butaner och disubstituerade cyklohexaner.

Elektrofil addition till alkener . period 1, HT-2014 'Kom Ihåg' från Molecular Movies KE0051:2 13:40:00, 1 oktober 2014 Anders Sandström Sida 2 / 12

An electrophilic addition reaction is an addition reaction which happens because what we think of as the "important" molecule is attacked by an electrophile. The "important" molecule has a region of high electron density which is attacked by something carrying some degree of positive charge. I det centrala innehållet för kursen i Kemi 2 står det bara ATT man ska ta upp några reaktionsmekanismer och energiomsättningar vid olika slags organiska rea An electrophilic addition reaction is a reaction in which a substrate is initially attacked by an electrophile, and the overall result is the addition of one or more relatively simple molecules across a multiple bond. The mechanism for the addition of hydrogen halide to propene shown in the reading is quite detailed.

Elektron arayan reaktifler olmalarından dolayı elektrofiller olarak tanımlanırlar 16 Katılma (addition) tepkimeleri, çoklu bağlı bileşiklere özgü tepkimelerdir.

Elektrofil u organskoj hemiji predstavlja reagens koji privlači elektrone, i koji učestvuje u hemijskim reakcijama tako što prihvata elektronski par kako bi se vezao sa nukleofilom.

For example, ethene + bromine → 1,2-dibromoethane: C 2 H 4 + Br 2 → BrCH 2 CH 2 Br Additionsreaktion, kemisk reaktion, hvor ét molekyle adderes til et andet molekyle, uden at der fraspaltes andre grupper. Aldehyder, alkener, alkyner, iminer, ketoner og carboxylsyrer samt derivater heraf kan indgå i additionsreaktioner.
