Homework Answers
first number the carbon chain to determine the carbon position.
to check each chiral carbon i.e all 4 attached is different.
then numbering the chiral carbon molecules as higher mass fir if same then check for next attached to that place.
for anticlockwise R configuration
for clockwise direction S configuration.
