What does ATI BR CH mean on jewelry
White gold= ATI BRCN LOOKS AS OF ITS PLATINUM AND YELLOW GOLD WHEN LOOKING AT IT AT AN
CH3-CH=CH-CH2-CH3 + Br2 = CH3-CH(Br)-CH(Br)-CH2-CH3
CH3-CH(Br)-CH(OH)-CH3
CH3-CH2-CH2-Br + KOH(alcoholic) = CH3-CH=CH2 + KCl + H2O CH3-CH=CH2 + HBr = CH3-CH(Br)-CH3 Markonikov's rule
One example: Numbers ch.31.
Cooking oils are unsaturated triglycerides so Bromine add up on pi bonds, R-CH=CH-(CH2)n-COOR + Br2 = R-CH(Br)-CH(Br)-(CH2)n-COOR , the confirmation of reaction is the decolourisation of Bromine.
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
The redish brown bromine color disappears by the addition of bromine to double bond.Br2 + H2C==CH-(CH2)n-CH3 ----> H2C(Br)--CH(Br)-(CH2)n-CH31-alkene ----> 1,2-dibroom-alkane
CH2=CH2-CH-CH2-Br 1-butene, 3- OH, 4-Br | OH Not sure but would be my best bet
The molecule CH3-HC=CH-Br can exist either in the cis or trans configuration.
It means the jewerly isn't made from real gold, but has the colour of 24 k gold. 'CH' stands for 'Cheap'
