Answer 2

It looks like you've provided a sequence of chemical symbols representing a hydrocarbon molecule. Each "С" likely represents a carbon atom, and "Н" represents a hydrogen atom. The numbers indicate the number of hydrogen atoms bonded to each carbon atom.

The sequence you provided can be interpreted as follows:

$\text{CH}_3 - \text{CH} = \text{CH} - \text{CH}(\text{CH}_3) - \text{CH}_3$

This represents a hydrocarbon chain with alternating single and double carbon-carbon bonds. The presence of $\text{CH}_3$ groups on the third and fifth carbon atoms indicates branching in the molecule.

It's important to note that this representation doesn't specify the exact spatial arrangement of atoms in three-dimensional space. For a more detailed understanding of the molecule's structure, a three-dimensional molecular model would be required. Additionally, if you have a specific name or systematic nomenclature for this molecule, it would provide more information about its structure and properties.
