Figure 10.4a Addition reaction. The reaction between C=C double bond and bromine (Br 2) can be used as a test for the presence of alkene in an unknown sample. The bromine reagent is in reddish color, and the product vicinal dibromide is colorless. When bromine is added to the sample, if the reddish color disappear, that means the sample does.

Question: Draw the product obtained when trans-2-butene. Draw the product obtained when trans-2-butene is treated first with Br2 in CH2Cl2, second with NaNH2 in NH3, and then finally with Li in NH3. Please show each step. There are 2 steps to solve this one.
Alkene + Br2 + H2O YouTube
Electrophilic addition of HBr H B r to an alkene: Step 1 is an acid-base reaction: the ฯ ฯ electrons of the alkene act as a base and extract the acidic proton of HBr H B r. This leaves one of the carbons with a new bond to hydrogen, and the other with an incomplete octet and a positive formal charge. In step 2, the nucleophilic bromide anion.

Stereochemistry of addition of Bromine to Cis and Trans-2-Butene. Bromine adds on to the cis isomer giving rise to (ยฑ)-2,3-Dibromobutane while the trans isomer leads to meso-Dibromobutane exclusively. These results are consistent with the two step mechanism with bromonium ion intermediate. The carbocation intermediate would have given rise to.
