(B) Anti form and gauche form have same torsional strain in butane about C2-C3 bond.

F-CH2-CH2-F, Gauche form has greater stability due to gauche effect, then anti form.

Q. Which statement is incorrect:

In ethylene glycol gauche form is more stable than anti form due to intramolecular $H -$ bonding.

Anti form and gauche form have same torsional strain in butane about $C_{2} - C_{3}$ bond.

In case of $X-CH_{2} -CH_{2} -X$ $[where X is halogen]$ , anti form is more stable than gauche form about $C - C$ bond, for all halogen

For skew form dihedral angle is $0^{\circ} < θ < 6 0^{\circ}$

$F - C H_{2} - C H_{2} - F,$ Gauche form has greater stability due to gauche effect, then anti form.

Q. Which statement is incorrect:

In ethylene glycol gauche form is more stable than anti form due to intramolecular H− bonding.

Anti form and gauche form have same torsional strain in butane about C2​−C3​ bond.

In case of X-CH2​-CH2​-X [where X is halogen] , anti form is more stable than gauche form about C−C bond, for all halogen

For skew form dihedral angle is 0∘<θ<60∘
