l6. 1TEST TUBE REACTIONS, I6.2 MASS SDECTROMETRY
chemcad Tests for tunctonal qroups
Alkene - shace with bromne water
Orange tucns colousless
Haloqenoalkane add acidified Aq NOz
prcupitate of Ag Xforms
Alcohol - add acudif1ed kceQ,
orange colow turns qreen with prmayr secondary
aohols or with aldehydes
Aldenyde wara wth Felalnq's solution
blue cclor tuns to ed prepitate
warm Lwith Iolen's solution
Silver mirror toms

- Eliaht ratio le{fect1vely relatue mass).
Detection
tragnentaton ons break up as some bonds break as theu
IDAise, so there are other ions ot Smale maleulr mass.
Moleulos on- eq cthono forms ion CzlHsOH
