is this optically active? if yes then how can we even check optical activity in bondline structure ?

Notice that there are 2 chiral carbon (2nd and 4th) but the whole structure itself is symmetric about the middle I think this is a meso compound Optically inactive

You actually can't say

Really?

Until you have the wedge structure

Oh is it the R and S configuration thing

Because the two chlorines on the left and write could be on different sides of the plane, so you won't have symmetry

What if it was just planar Which I think is the assumption when just given a bond line structure Actually it can't be Nvm Alr VSEPR just vanished from my head for a sec there

First one has plane of symmetry. Second one doesn't.

so all in all just from bondline structure we cant determine if compound is optically active or inactive ok so to make optical isomers of a compound is it necessary for it to be optically active ?? i dont understand the relation between optical activity and formulation of optical isomers

you generally dont, but since it is obvious here that there is sp³ carbons. So their are many non planar atoms, hence, there doesn't exist a Plane of symmetry.
