It's so hard to visually do this. -_-

@campbell_st

anonymous · Answer

first answer is going to be J, It's kinda hard to visualize, but imagine you're twisting the compound around the C-C bond in a clockwise rotation

anonymous · Answer

The hydrogen should now point outward, the OH backward, and the CH3 with the solid line

anonymous · Answer

Indeed very hard. -_-
@alias : Can you please explain if all the carbon atoms in this molecule are coplanar?

anonymous · Answer

The only configuration that give you a plane is when you have steric number 3, because then the geometry of your molecule around that atom will be trigonal planar

anonymous · Answer

what's the steric number around the carbon? And what's the name of the geometry that it forms?

anonymous · Answer

Tetrahedral?

anonymous · Answer

@alias : The steric number is 4, right? So that means carbons in this molecule will not be planar?

anonymous · Answer

yup, you got it! Tetrahedral has a 3D shape, and is not planar AT ALL
