b)
Interpretation:
To assign E or Z configuration for the compound given.
Concept introduction:
The two groups attached to the carbons in double bond are to be ranked first. The member that ranks higher can be determined by considering the atomic number of the first atom of the two substituents separately. The atom with highest atomic number gets the higher rank. If a decision cannot be made by considering the atomic number of the first atom in each substituent then the second, third, fourth atoms away from double bond are considered until the first difference is found. Multiple bonded atoms are considered as equivalent to the same number of single bonded atoms. The isomer that has the higher ranked groups on each carbon on the same side of the double bond is said to have Z configuration. If the higher ranked groups are on the opposite sides, the alkene is said to have E configuration.
