Answer 1

3,5- диметилгексен-1

Answer 2

Based on the chemical formula you provided, it appears to be a representation of a molecule consisting of carbon and hydrogen atoms. However, the nomenclature is not clear, and there seem to be some syntax errors in the notation. It's challenging to provide a precise name without proper chemical notation.

If you could provide a clearer and correctly formatted chemical formula or name, I would be more than happy to help you identify the molecule.
