Vedclass · Answer

(D) The stability of the Gauche form in molecules like $Z-CH_2-CH_2-OH$ is often enhanced by intramolecular hydrogen bonding between the $-OH$ group and the group $Z$.For intramolecular hydrogen bonding to occur,$Z$ must be an electronegative atom or group capable of acting as a hydrogen bond acceptor (e.g.,$-F$,$-OH$,$-OCH_3$,$-NH_2$,etc.).Since $-F$,$-OH$,and $-OCH_3$ can all participate in intramolecular hydrogen bonding with the $-OH$ group in the Gauche conformation,the Gauche form becomes more stable than the anti form in these cases.Therefore,all of these groups make the Gauche form stable.

The given Gauche form is stable when $Z$ is:
