A turn-of-the-century chemist isolated an aromatic compound of molecular formula C6H4Br2. He carefully nitrated this compound and purified three isomers of formula C6H3Br2NO2. Propose structures for the original compound and the three nitrated derivatives.

the structures are shown in the image attached.

Explanation:

Before the invention of mordern spectroscopy, Korner's absolute method was commonly applied in determining whether a disubstituted benzene derivative was the ortho, meta, or para isomer. Korner's method depends on the addition of a third group, nitro groups are usually added. The number of isomers formed is then determined. The isomers are usually obtained only in small amounts and analysed to know the structure of the original compound.

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this
