(S)-2-chloropentane has a specific rotation of +34.07°.
(i) Show the structure of (S)-2-chloropentane.
(ii) What is the specific rotation of (R)-2-chloropentane.
(iii) If a sample containing (R)- and (S)- 2-chloropentane has a specific rotation of –12.47°, calculate the percentage composition of the sample. 

• A. (i)(ii) –34.07°(iii) %R = 68.30%; %S = 31.70%
• B. (i)(ii) –34.07°(iii) %R = 68.30%; %S = 31.70%
• C. (i)(ii) –34.07°(iii) %R = 31.70%; %S = 68.30%
• D. (i)(ii) –34.07°(iii) %R = 31.70%; %S = 68.30%
