The correct statement regarding the given equilibrium is?
1
The equilibrium favors the anti conformer because the steric hindrance between the F and NH2+ groups is minimized.
2
The equilibrium favors the gauche conformer due to weak hydrogen bonding between the lone pairs of F and one of the hydrogens on NH2+, stabilizing this form.
3
The equilibrium is equally distributed between the anti and gauche conformers as both forms have similar electronic and steric interactions.
4
The equilibrium favors the anti conformer because the gauche interaction increases torsional strain and destabilizes the molecule.
