The interchange of two groups `(Br`and `CH_(3)` at the chiral centre of the projection formula `(A)` yields the fromula `(B)`,while the interchange of another set of two groups `(C_(2)H_(5)` and `CI)` of `(A)` yields the projection formula `(C )`.

Which of the following statemenets is not correct about the structures `(A),(B)` are `(C )`?

Which of the following are correct statements about C_(2)H_(5) Br.

Which of the following are correct statements about C_(2)H_(5) Br.

The prefixes 'erythro' and 'threo' are used for distinguishing a pair of enantiomers containing two chiral carbon atoms when two of the atoms or groups on each chiral carbon atom are the same while the third is different. The stereoisomer, in which the two identical groups are on the same side of the Fischer projection formula, is called the erythro isomer while the isomer, in which the two identical groups are on the opposite sides of the Fischer projection formula, is called the threo isomer. Select the correct statement about the following compound:

Write the structural formula for seven compounds with the formula C_(3) H_(6) O and identify the funcitonal groups.
