Increasing order of stability among the three main conformation (i.e. eclipse, anti, gauche) of ethylene glycol is :

Options

  1. AEclipse< gauche< anti
  2. BGauche
  3. CEclipse< anti< gauche
  4. DAnti< gauche< eclipse

Correct answer

C. Eclipse< anti< gauche

Step-by-step solution

C H 2 O | H - C H 2 O H | in gauche intramolecular H -bonding is taking place so it is highly stable among all.in staggered anti steric repulsion is less as eclipsed so it is more stable than eclipsed Stability order &#8658; Gauche &#62; Anti &#62; Eclipse
