Concept explainers
(a)
Interpretation : The structure of (R)-3-bromo3-methylhexane needs to be drawn.
Concept Introduction : The R and S configuration is decided by the direction of rotation of the molecule about a plane.
(b)
Interpretation : The structure of 3, 5-dimethylheptane molecule needs to be drawn.
Concept Introduction : The configuration shows in chiral atom. When four different groups attached to the single atom that atom is called chiral atom.
(c)
Interpretation : The structure of 2-bromo,3-methylpentane needs to be determined.
Concept Introduction : If the 4th priority group is below the plane and rotates clockwise then that molecule has R configuration in it.
(d)
Interpretation : The structure of 1,1,2-trimethylcyclopropane needs to be drawn.
Concept Introduction : The configuration of molecule decided by the direction of the rotation of the chiral atom about the plane axis.
(e)
Interpretation : The structure of 1-choloro, 1-trifloromethyl-2-methylcyclobutane and 1,2-dichloro,3-ethylcycclohexane needs to be drawn.
Concept Introduction : The configuration of the molecule follows the Cahn-Ingold-Prelog priority rules. Clockwise rotation represents the R configuration and anticlockwise shows the S configuration.
