What do you think jefferson meant by "natural rights"

Life liberty and the pursuit of happiness are what he lists as "natural rights". I think he meant that every human should be born with these rights and they therefore "natural". He meant that these rights come with being human, and do not have to be earned.

Ifound the exercise on the internet. attached is the list mentioned above.in order for a compound to be considered optically active it can't have any axis or plan of symmetry. the molecule  shouldn't also  be superimposable on its mirror image.with such considerations, the compounds that are optically active are: -third compound on the first image is optically active; -second and third compound from the second image are optically actives.
