Part A

Part B

the-CH-C - CH-cooo Stereoisomers are! SO-isomer z anti clock wise opeo 1 C- CH - CH - C - coo o "H / anticlockwise but stereochemistry is reversed as H l onest priority group is above the plane So, it is R-isomer. thence, streoisomes are the C-CH-CH₂-C - Coo- HC - - -C-Coo- CHIN (S)-Leucine (Also L-Leucine) (Rt Leucine (Also D-Leuune)
