Chapter 3, Problem 69IP

An aldehyde/ketone plus an alcohol gives a hemiacetal, and an excess of alcohol gives an acetal. The reaction is an equilibrium; in aldehydes, it's shifted to the right and in ketones, to the left. Explain.

Draw a Haworth projection or a common cyclic form of this monosaccharide: H- -OH H- OH H- -OH CH₂OH

Ggggffg2258555426855 please don't use AI   Calculate the positions at which the probability of a particle in a one-dimensional box is maximum if the particle is in the fifth energy level and in the eighth energy level.

Explain the concepts of hemiacetal and acetal.

Briefly describe a nucleophilic addition.

Is nucleophilic acyl substitution an SN1 or SN2 reaction?

Draw product A, indicating what type of reaction occurs. NH2 F3C CF3 NH OMe NH2-NH2, ACOH A

Photochemical smog is formed in part by the action of light on nitrogen dioxide. The wavelength of radiation absorbed by NO2 in this reaction is 197 nm.(a) Draw the Lewis structure of NO2 and sketch its π molecular orbitals.(b) When 1.56 mJ of energy is absorbed by 3.0 L of air at 20 °C and 0.91 atm, all the NO2 molecules in this sample dissociate by the reaction shown. Assume that each absorbed photon leads to the dissociation (into NO and O) of one NO2 molecule. What is the proportion, in parts per million, of NO2 molecules in this sample? Assume that the sample behaves ideally.
