EBK CHEMISTRY: ATOMS FIRST
- The curved arrow notation introduced in Section 1.6B is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions.Because each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCl.arrow_forwardDraw resonance structures for the following compound:Add curved arrow(s) to show resonance using one of the five patterns, and modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.arrow_forward2) Draw the Lewis structures first and then complete the following acid-base reaction by using appropriate arrows. Acid and base should be labeled. CH3CHBRCOOH + NaHarrow_forward
- Which of the following shows correct arrow placement that represents significant resonance for the given molecule? None of the choices given represent significant resonance. Save for Laterarrow_forwardDraw the curved arrows and the resulting resonance structure for the following structure. Include lone pairs and charges in your structure.arrow_forwardUnshared, or lone, electron pairs play an important role in determining the chermical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. The number of unshared pairs at atom a is The number of unshared pairs at atom b is HyC CH The number of unshared pairs at atom e is The number of unshared pairs at atom a is The number of unshared pairs at atom b is HC CH The number of unshared pairs at atom e isarrow_forward
- Give a reasonable set of resonance structures for each compound below. Use Resonance Arrows, and curved arrows, and brackets to draw a proper set of resonance structures.arrow_forwardDraw all reasonable resonance structures for the following species. :0: draw structure . draw structure . negative charge on carbon negative charge on oxygenarrow_forwardThe carbon atom owns one electron from each of shared pairs and two electrons from unshared pair. The number of electrons that belong to carbon is . Carbon is a Group element. Since the carbon atom has one more electron than it would in the neutral, unbonded state, it has a formal charge of –1 . The Lewis structure for the methyl anion is The lithium fragment must have a formal charge ofarrow_forward
