Verified step by step guidance
1
Identify the chiral center in compound A, which is the carbon atom at position 2 in 2-butanol, and note that it has the configuration R1 (R configuration).
Assign priorities to the substituents attached to the chiral center according to the Cahn-Ingold-Prelog (CIP) priority rules, based on atomic number and connectivity.
Determine the absolute configuration (R or S) of each given compound by assigning priorities to their substituents and analyzing the spatial arrangement.
Compare the absolute configurations of the given compounds to that of compound A (R-2-butanol) to find which one matches exactly.
Conclude that the compound with the same absolute configuration (R) and the same substituents arrangement as compound A has an identical configuration.
