Hi there,

Thank you for asking BrainMass! Please find solutions in the attached document.

All the best with your chemistry course.

Organic Chemistry Part IV

1- Draw a structure for each alkane.
A- 2,2-dimethylpentane

To draw, begin with the longest chain (pentane). Add in two methyl groups on the second carbon of the pentane chain to complete the molecule.

CH3
