Determine if the following pairof molecules is isomers or conformers?

For rotation about the C-3---C-4 bond of 2-methylhexane, do the following:

c. About which other carbon–carbon bonds may rotation occur?

d. How many of the carbon–carbon bonds in the compound have staggered conformers that are all equally stable?

Although there is free rotation around most σ bonds, rotation is restricted around the C--N bond of an amide. Explain why this is true.

Determine if the following pair of molecules isisomers or conformers?

Determine if the following pairof molecules is isomers or conformers?
