Q.Silver propionate when refluxed with bromine in carbon tetrachloride gives a) propionic acid b) chloroethane c) bromoethane d) chloropropane

Step 1. Silver propionate, CH3CH2COOAg, refluxed with bromine in CCl4 is the Hunsdiecker reaction.

Step 2. The silver carboxylate loses CO2 and AgBr, and the remaining alkyl fragment picks up the bromine that was released -- so the three-carbon propionate (CH3CH2COO-) becomes the two-carbon bromoalkane CH3CH2Br, one carbon shorter than the starting acid salt. …

Recall the Hunsdiecker reaction removes CO2 from the silver carboxylate and installs the halogen from Br2 in its p …

• Answering chloropropane by mistaking the CCl4 SOLVENT for the source of the halogen incorporated into the product -- the halogen that ends up in the pro …
