Question

Rotation of one conformer by an angle between 0° to 60° generates ______. 

विकल्प

• staggered form

• eclipsed form

• gauche (skew) form

• none of these

Answer 1

Rotation of one conformer by an angle between 0° to 60° generates gauche (skew) form. 

Explanation:

Any arrangement that falls between the two extreme structural forms, staggered and eclipsed, is referred to as a gauche (skew) form. Rotation of 0° to 60° produces gauche (skew) form, while rotation of 60° transforms staggered into eclipsed form and vice versa.
