In which of the following representations given below spatial arrangement of group/atom Is not different from the given in structure 'A' ?

Options

A.
B.
C.
D.

Answer

B

Explanation

By making two interchanges of atoms or groups of atoms, bring H below the plane of the paper and then find out the sequence of the remaining three atoms or groups in a particular order i.e. clockwise or anticlock wise starting from atom with highest atomic number (Br) and moving towards lower atomic numbers,
`(i.e. Br to CI to CH_3)`.


(a), (c) and (d) have different (anti-clockwise) spatial arrangement of atoms or groups of atoms than that given in structure = A (clockwise)
