MUUT ULUUIU CUhformer of 2-fluoro ethanol among the following: Η | Η HO H (Β) Η Η Ι Η Η (C) (C) TOH (D) Η-() HOF

Conformations are different arragements of atoms htat are interconverted by rotation about single bond. IN eclipsed conformation, the C-H bond on one carbon is directly aligned with C-H bond on the adjacent carbon. In staggered conformation, the C-H bond on one carbon bisect the H-C-H bond angle on adjacent carbon. The angle that seperates a bond on one atom form a bond on a adjacent atom is called a dihedral angle. A staggered conformation with two larger groups 180^(@) from each other is called anti. A staggered conformation with two larger group 60^(@) from each other is called gauche Identify the most conformer of 2-fluoro ethanol among the following:
