See the Attachment & Answer the following question?  Stalevo is the trade name for a medication used for Parkinson's disease,which contains L-dopa, carbidopa, and entacapone. Ques: Use curved arrows to draw a resonance structure that is an equalcontributor to the resonance hybrid ?

Answer the following question about the molecule shown below. Certain C,C single bonds are labeled I - III. لات H Select one: OA. I OB. II H H OC. III Which is the shortest C,C single bond? www. Clear my choice H

Which model, the ball-and-stick or the space-filling, more effectively showsthe angles between bonds around a central atom?

D a Given that the spatial requirement of a lone pair is greater than that of a bond pair, explain why XeF2 has a linear molecular structure and not a bent one. The four lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 180°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The three lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 120°, so there is less lone pair/lone pair repulsion with this arrangement. Submit

Suppose all the hydrogen atoms in this molecule are replaced by chlorine atoms: H. N N-H Draw a skeletal ("line") structure of the new molecule. Be sure you follow all the usual rules for drawing skeletal structures.

Write the condensed structure of a compound that contains only carbon and hydrogen atoms and that has. please help with al parts

One, or both, of the following structural formulas may be incorrect (i. e., they do not represent a real compound) because they have atoms with an incorrect number of bonds. Which of the labeled atoms have the incorrect number of bonds? Specify the incorrect atoms by letter in alphabetical order without spaces or commas., i.e. bd. If there are no incorrect atoms, write none. a) b) H H lb lc d -C-0-H a H-N -C H bN H H

Draw a line-bond structure for C₂H₂. • Explicitly draw all H atoms. • You do not have to include lone pairs in your answer. • In cases where there is more than one answer, just draw one.

Which would be correct please? do I separate the OH?
