a.
Interpretation:The structure of trans -1,2-cyclohexanediol should be drawn in the chair form where both hydroxy groups are at equatorial.
Concept introduction: In cyclohexane, all the six carbons are sp3 hybridized so, the expected angle for the connected atoms will be
b.
Interpretation:The flipping of chair during the transformation of trans -1,2-cyclohexanediol to corresponding disilyl ether on reacting with chlorosilane needs to be explained by structural models.
Concept introduction:In cyclohexane, all the six carbons are sp3 hybridized so, the expected angle for the connected atoms will be
