Draw the structures of all monofluoro derivatives of methylcyclopentane, c6h11f, which have the fluorine on a tertiary carbon.

1) Do you know what is a tertiary carbon?

They are carbons attached to othe three carbons

2) Do you know the structue of methylcyclopentane?

It is a cyclopentane molecule with a CH3- group attached to one carbon

3) Do you know which carbons are tertiary in methyl cyclopentane?

The only tertiary carbon in methyl cyclopentane is the carbon to which the methyl (CH3) group is attached.

4) So, there is just one monofluoro derivative of methylcyclopentane with the fluorine on a tertiary carbon: it is the  1-fluoro-1-methyl-cyclopentane.

I also attach the drawing

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
