An unknown Compound D (molecular formula: C6H5NO) forms a silver mirror in a Tollens test and is soluble in aqueous HCl. The IR spectrum of Compound D displays several absorption peaks including peaks at 3070 cm-1 and 1700 cm-1 . 1H NMR data for Compound D as follows: Compound A: 9.7 ppm (singlet, 1H), 8.2 ppm (doublet, 2H), 7.5 ppm (doublet, 2H) Propose a structure for Compound D. Explain your answer using all of the information given. For the 1H NMR spectrum, be sure to label your compound to clearly outline all information for your peak assignments.

What causes different colors to appear in the sky? the absorption of light by air molecules the reflection of light by bodies of water the greenhouse effect in earth's atmosphere the scattering and reflection of light by dust particles

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
