Can the following compound having a centre of symmetry be called both optically inactive and meso? The Centre Of Symmetry (COS) has been shown by a blue dot.


My questions are:

Can this molecule be called optically inactive? I have this doubt because single bonds permit free rotation and the molecule hardly
remains in the given form for long.
Can this molecule be called a meso-compound as it optically inactive?
Slightly unrelated: I'm actually a bit confused with the definition of meso. I learnt that meso compounds must have a plane of symmetry. Am
I correct?

According to Wikipedia a meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active.
Update: I realized my mistake in thought procedure after asking the question.(I fell into the &quot;Meso Trap&quot; :-P )
I would like to add this link as it might help future viewers.

You are correct that the molecule is not chiral. It is indeed a meso compound due to the internal symmetry plane. Also, don't worry about free-rotation of single bonds.
