Question

Can you please tell me if these are ortho, meta, or para?

Answer 1

You can't label these compounds as ortho, meta or para. Only substituted aromatic compounds, specifically benzene compounds are named like this. The compounds mentioned here, don't fall into that category.

With respect to the reference group,

i) 2- and 6- substitutions are called ortho;

ii) 3- and 5- substitutions are called meta &

iii) 4- substitutions are called para.
