Bond Angles of equatorials and axials

[Kristen_Power_1C]

In determining where the equatorial and axial bonds should go, is it all just dependent on making sure you are making the appropriate angles of 109.5 degrees between the closest atoms? I'm a little confused to how you should know where to place them.

[Kareem]

Equatorial and axial alternate, so make sure that you are alternating between the different carbons and their bonds.

If the problem asks for the mot stable conformation, then you want to put the biggest substituents of the cyclohexane on the equatorial position.

What are the bond angles for a ethane and butane when they are both in staggered or in eclipsed conformation?
