2) Draw the Lewis structures first and then complete the following acid-base reaction by using appropriate arrows. Acid and base should be labeled. CH3CHBRCOOH + NaH

which of the following compounds has the smallest number of acidic hydrogen atoms? HC4H7O2, H2C2O4, H2C4H4O4, H3PO4, H2C3H2O4, NH3

Decide whether each of the molecules in the table below is stable, in the exact form in which it is drawn, at pH=2. If you decide at least one molecule is not stable, then redraw one of the unstable molecules in its stable form below the table. (If more than one molecule is unstable, you can pick any of them to redraw.) OH OH HO Ostable Ounstable O stable Ounstable HO Click and drag to start drawing a structure. stable Ounstable O stable Ounstable ☐ X 口: G EX olo

This is a Brønsted-Lowry acid-base reaction. Draw structures for all the products, showing any non-zero formal charges in each one. Make sure your reaction is balanced. Note for advanced students: Draw only the most stable resonance structure for each product. NH2 CH,-CH-CH-CH, Click and drag to start drawing a structure. HCI CH, 1
