Using curved arrows draw all the resonance structures for the following ion. Note that all the charges are as shown but the lone pairs of electrons might be omitted so, add the lone pairs to help you track the movement of electrons. Br 6 HO OH 2 5 1 4 7 8 9 a) If a Nucleophile were to react with the given ion, at which position(s) will it react? Attach File Browse Local Files Browse Content Collection

for part b）why do we write AlCl3 at top of the arrow and AlCl4 at the bottom of arrow？？is it any connection between the two？does it means that AlCl 4 need to be present in order to make AlCl3 reacts to the molecule and make the reaction to process？？   2. why when AlCl3 added，Cl was removed from the ring？what princeiple theory is that ？   2. when SO3 is added ，SO3 attached to the ring，why ？what principle is behind this phenamonane   3.Just confused about why AlCl3 removes Cl from the ring，while HSO3 donate SO3 to the ring. Is it Something about nucleohilic or eletrciohillic？

naming a chemical compound. I'm currently learning how to name alkanes and alkyl halides. Im confused about the compound ethanal, or acetaldehyde. The second carbon has a double bond on its hydrogen, so I'm wondering why the infix is "an" instead of "en". Frpm the table of infixes, it says "an" is for single bonds. Can someone help me understand

The organic acid propanoic acid will react with the organic base cyclohexylamine. *O* H . All hydrogen atoms are implied, except: ● a Draw the structures of the products of this neutralization reaction. H H o Hydrogen atoms not attached to carbon atoms o Hydrogen atoms involved in the mechanism **** Apply formal charges where appropriate. Assign lone pairs and radical electrons where appropriate. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. . Separate multiple products using the + sign from the drop-down menu. ● If needed, use the "starting points" menu to revert to the original molecule(s) shown. ? Sn [F]
