[Review Topics] [References] Draw structural formulas for the alkoxide ion and the alkyl(aryl)bromide that may be used in a Williamson synthesis of the ether shown. CH3 CH3CH2CH2CH2–0-0- CH , • You do not have to consider stereochemistry. • Do not include counter-ions, e. g., Na, I, in your answer. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. с ору P aste > *** ChemDoodle​

Which supports the idea that birds and butterflies both have wings but they do not have a common ancestor with wings? a. the wings are analogous structures that evolved differently and do not have a similar internal structure. b. the wings are homologous structures that evolved differently and do not have a similar internal structure. c. wings of birds are vestigial structures, but the wing structures of bats are not vestigial. d. wings of bats are vestigial structures, but the wing structures of birds are not vestigial

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?
