Solution

The correct option is B analogous in absolute configuration to (R)-2-chloropentane
(R)-2-Bromopentane is optically active with one chiral carbon, hence in the absence of specific data, it can only be said that (R)-2-bromopentane is analogous in absolute configuration to (R)-2-chloropentane.

in absence of Aufbau Principle.

Q. The D, L system of relative configuration is not 100% correct, and hence R, S system was adopted as a defect proof, absolute configuration. The R, S system involves the following steps:
Step l: The four atoms or groups attached to the chiral carbon atom are assigned a sequence of priorities according to sequence rules.
Step ll: The arrangement of these four atoms is observed by drawing a curved arrow from the atom with the highest priority (1) to the atoms with next highest (2) and if the direction of this arrows is clockwise it indicates R configuration. While the anticlockwise direction from group (1) to group (2) indicates S configuration. However, this convention is true only when the atom with the lowest priority (4) is present on the vertical bond, in case of Fischer projection. In case, the atom (4) lies on the horizontal bond opposite configuration is assigned.
