stability and (R or S) configuration OTA#104318

This is a very simple problem. I chose and explain which one of the chair conformations is more stable. Then I need assign (R or S) configuration to two molecules and determine if they are optically active.

(a) Which conformer, K or L is predicted to be more stable? Explain
your answer (Note: a methoxy group is smaller than a methyl group). (b)
Assign the absolute (R or S) configurations for each of the chiral
carbons in carbohydrates M and N. Are either of these compounds
optically active? Briefly explain your answer.
