In which of the following representations given below spatial arrangement of group/ atom different from that given in structure ‘A’?
The answer is the option (i), (iii) and (iv)
Explanation: The spatial arrangement of groups of atoms can be checked by interchanging and bringing the H below the plane of the paper and then finding out the sequence of the remaining groups in a particular order whether clockwise or anticlockwise where it is started from the atom with the highest atomic number to the atom with the lowest atomic numbers.
