Can we rotate a mirror image by any angle to check if it is superimposable? [closed]
A molecule is chiral when it is different from its mirror image, and achiral if it is identical to its mirror image. To check if the mirror image is identical to the original object, we have to check ...

Does no optical rotation always implies optical inactivity? [duplicate]
This question popped up in my mind in reference to this question,
Is a compound optically active if plane polarised light is deflected by an angle of n*(2π) angles?
Suppose that I give a chemistry ...

Conditions for Chirality in optical isomerism [duplicate]
Is it necessary that any atoms which is chiral must have 4 different atoms around the central chiral atom(maybe it can be carbon if it's organic molecule) bonded to it?
More specifically:
I mean can't ...
