In the given conformation, if `C_(2)` is rotate about `C_(2)-C_(3)` bond anticlockwise by an angle of `120^(@)` then the conformation obtained is

In the given conformation C_(2) is rotated about C_(2)-C_(3) bond by 120^(@) , then the conformation formed will be

The number of conformational isomers possible of n-butane about C_(2)-C_(3) bond

Newman projection of Butane is given, C-2 is rotated by 120^(º) along C_(2)-C_(3) bond in anticloclwise direction, the conformation formed is :

In the above compound, C_(2) is rotated clockwise 120^(@) about C_(2)-C_(3) bond. The resulting conformer is:

In the above compound, C_(2) is rotated clockwise 120^(@) about C_(2)-C_(3) bond. The resulting conformer is:

The line joining the points A(3,0) and B(5.2) is rotated about in the anticlockwise direction through an angle of 15^(@). If B goes to C in the new position now the line joining A and C is roteted about A in the anticlockwise direction through an angle of 45^(@) of C goes to D are. the coordinates of D are.
