(a)
Interpretation:
The most stable chair conformation of the given molecule is to be drawn.
Concept introduction:
The stability of chair conformation of the six member ring having heteroatom is the same as the cyclohexane ring. The presence of heteroatom in the ring is at any place which is similar to carbon.
The most stable chair confirmation of disubstituted cyclohexane is the one in which the substituents experience the least amount of strain. This is when the larger substituent occupies an equatorial position. In disubstituted cyclohexane, the substituents which are on the same side are cis to each other whereas substituents which are on the opposite side of the ring are trans to each other. If there is more than one substituent attached, the conformation in which maximum substituents are in equatorial position is favored and is more stable. Substituents that are trans to each other in one chair conformation remains trans after the chair flip.
