- Draw all possible resonance forms for anisole using appropriate arrow notation. Which resonance structure is most stable? Which is least stable? Draw the resonance hybrid for anisole, indicating all partial charges.The curved arrow notation introduced in Section 1.6 is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions. Since 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.The curved arrow notation introduced in Section 1.6 is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions.

- Draw all resonance contributors for each of the following molecules or ions. Be sure to include the curved arrows that indicate which pairs of electrons are shifted in going from one resonance structure to the next. (a) CH3NO2 (b) CH, CO, (c) CH CHCHCH2 (the ion has two C-C single bonds) (d) C5H5N (a ring is formed by the C and N atoms, and each H is bonded to a C atom) (e) C4H5N (a ring is formed by the C and N atoms, and the N is bonded to one H atom, and each C atom is bonded to one H atom)3. The following shows all resonance structures for the following molecule. a. Draw in all implied lone pairs. b. Draw in curved arrows that show the flow of electrons, making sure the arrows show the precise starting point and destination of the electrons. Label each arrow as: lp →→→л (p=lone pair) c. d. Rank the resonance structures from most stable to least based on the number of formal charges and atoms that lack an octet of electrons. ol-of-o.

- Stuck on this section questionThe two molecules in the pictrue behave very differently in reactions. Though they are both neutral, it is possible to draw resonance structures to illustrate which atoms will have partial charges. In one of the molecules, a carbon of the double bond is partially positive while in the other it is partially negative. 1. Draw one resonance structure for each molecule below with only one positive and one negative charge in the left box. In the box to the right draw out the original structure with its partial charges, which can be determined from the resonance structures.Draw an arrow pushing pattern represents the flow of electrons that converts the first resonance structure into the second resonance structure?

(choose correct letter from A – D): A. two double bonds C. two single bonds B. a single & double bond D. a double & triple bond d) Fill in the table below for BeAt2. For prediction of the actual bond angle, if the angle is ideal give the numerical value; if the angle is different from ideal use > (greater than) or < (less than) with the numerical value of the ideal bond angle (for e.g., < 1800). { NOTE: i) The correct spelling of the names matters. Be sure to check your spelling.ii) For the hybridization, place the superscript numbers on the same level as the letters.
