1. The correct name of the compound on the right is- A) (R)-2-chloro-3-ethylpentane B) (S)-2-chloro-3-ethylpentane C) (R)-4-chloro-3-ethylpentane D) (S)-4-chloro-3-ethylpentane E) (R)-1-chloro-1-methyl-2-ethylbutane (ATOMIC NUMBERS are: H = 1, C = 6, CI = 17) 2. What is the correct order of the Cahn-Ingold-Prelog ranking of the following substituents as used in assigning R and S configurations of chiral centers? (higher ranking > lower ranking) (ATOMIC NUMBERS are: H = 1, C = 6, O = 8, Br = 35) -CH2OH -CHO (aldehyde group) A) -OCH3-CH2CH2Br > -CH2OH > -CHO C) -OCH3-CH2CH2Br > -CHO > -CH₂OH E) -OCH3> -CHO > -CH₂OH > -CH2CH2Br -OCH3 -CH2CH2Br B)-CH2CH2Br > -OCH3 > -CH2OH > -CHO D) -CH2CH2Br > -OCH3 > -CHO > -CH₂OH 10
