10. Give the structures for compounds E and F in the sequence of reactions shown below. (2 points) Compound E 1. NaNH2, NH3 2. CH₂CH₂Br Compound F H₂O, H₂SO4 HgSO4

Complete each acid-base reaction and predict whether the position of equilibrium lies toward the left or toward the right. (a) CH3CCH+CH3CH2ONa+CH3CH3OH (b) CH3CCCH2CH2OH+Na+NH2NH3(l)

The following Walden cycle has been carried out. Explain the results, and indicate where Walden inversion occurs.

There are no important resonance structures for the isopropyl cation CH3C+HCH3 because there are no in the structure. There are no important resonance structures for dimethyl ether CH3OCH3 because, although there are pushable electrons on the oxygen atom, there is no . There are no important resonance structures for the 5-pentenyl cation H2C=CHCH2CH2C+H2 because the pushable electrons and the receptor are separated by two methylene groups. Thus, the electrons have no way to get to the receptor.

Are endothermic reactions favorable or unfavorable? ... uphillor downhill?

Camphor, a saturated monoketone from the Asian camphor tree, is used among other things as a moth repellent and as a constituent of embalming fluid. If camphor has M+=152.1201 by high-resolution mass spectrometry, what is its molecular formula? How many rings does camphor have?

Complete each Lewis structure, draw all important resonance structures, predict a value for thebond angles requested, and explain your reasoning. a. Nitrous acid (HNO2)HONOHON=ONO= b. Enolate ion (C2H3O) HC1C2=HC2C1=
