a) -CH3, -OH, -H, -Cl
Interpretation:
The substituents in the set, -CH3, -OH, -H, -Cl, are to be ranked according to the sequence rules.
Concept introduction:
The member that ranks higher can be determined by considering the
To rank:
The substituents in the set, -CH3, -OH, -H, -Cl, according to the sequence rules.
b) -CH3, -CH2CH3, -CH=CH2, -CH2OH
Interpretation:
The substituents in the set, -CH3, -CH2CH3, -CH=CH2, -CH2OH, are to be ranked according to the sequence rules.
Concept introduction:
The member that ranks higher can be determined by considering the atomic number of the first atom in each substituent. 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 can be considered until the first difference is found. Multiple bonded atoms are considered as equivalent to the same number of single bonded atoms.
