In the molecule testosterone, what are all the chirality centers? State the R or S configuration.

In the structure of caffeine, where is the site with the most delocalized electrons?

My professor said that the answer was incomplete and incorrect

Consider 1-bromo-3-isopropyl-4-methylcyclohexane. All three substituents are on the same face of the ring (all top face or all bottom face). Draw the most stable chair conformation. State whether each substituent is axial or equatorial.

Consider 2-fluorobutane, sighted along the C2-C3 bond. Name the substituents on C2 and C3. Draw all the different Newman conformations. Finally, rank them from most stable to least stable.

Thanks! =)

What is the skeletal structure of 5-tert-butyl-3-isopropyl-4,7-dimethyldecane?

Thank you! =D

Redraw caffeine and draw the non-bonding electron pairs if any. Encircle the site with the most delocalized electrons. Then, identify the hybridization of the indicated atoms.

Help me please and thank you. Redraw acetaminophen on your paper and draw the non-bonding electron pairs if any. Encircle the site with the most delocalized electrons. Then, identify the hybridization of all the carbons in the structure.

Please help me, thank you!

Consider 2-fluorobutane, sighted along the C2-C3 bond. Name the substituents on C2 and C3. Draw all the different Newman conformations. Finally, rank them from most stable to least stable.

Thank you!

Help me please! Recall that in the Newman projection of ethane, there are no substituents (non-hydrogens) on either carbon. As a result, there are only 2 conformations: Staggered and Eclipsed. For the Newman projection of propane, sighting along the C2-C3 bond, there is 1 substituent on the front ca...

Is this better?

is this correct?

just 1

=D

I'm sorry, I don't get it. Could you possibly explain more please? =D

Draw the resonance structures of the following compound. Use curved arrows to show movement of electrons. Do not forget to include the given structure as one of the resonance structures. Identify whether each structure is either a major or minor contributor.
