Show curved arrows to indicate the flow of electrons. Show
appropriate charges and/or lone electron pairs to initiate electron
movement. Show any bonds that must be explicitly drawn when
transferring bonding electrons.

please go into detail with lone pairs and and electron pushing
arrows as well as formal charges! thank you!
Section II. Mechanism (100 pts) Provide the Mechanism for the Given Reaction Scheme (pay attention to charges and lone pairs) Write the answer below. The substrates given do not show electrons, however when writing your mechanism you must show all lone pairs furthermore electron pushing arrows must be drawn accurately. Additionally, you must show any/all formal charges. Good luck! olyte E18C/

1.2.3.4.5.6.7.8.Show the curved arrow mechanism for the reaction between ethoxide and methanol to give ethanol and the methoxide ion. 1st attempt Jual See Periodic Table See Hint OH-Ö: Add the missing curved arrow notation.The carbon-metal bond in organometallic Grignard reagents exhibits significant covalent character. However, we can treat these compounds as electron-rich carbanions because of the large difference in electronegativity between carbon and magnesium. These reagents are great to form carbon-carbon bonds but must be kept in an anhydrous environment...
