The stereochemical product should be drawn and identified for the given E 2 elimination reaction. Concept Introduction: Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E 1 (the reaction depends only on the substrate involved in the reaction) or E 2 (the reaction depends on both of the substituents in the reaction) mechanism. E 2 Elimination reaction: E 2 elimination occurs in a compound when the leaving group is antiperiplaner to the proton in presence of strong base. If the base is bulky in nature, least substituted alkene is favorable and the base is not bulky and stronger in nature, most substituted alkene is the favorable product. For E2 elimination reaction, proton should be present at β position to the leaving group in antiperiplaner way. Zaitsev’s Rule: It is elimination reaction in which the formation of olefin on most hindered or highly substituted position

1. Show that the change in entropy for a fixed amount of ideal gas held at a constant temperature undergoing a volume change is given by the simple equation AS = NkB In Hint: Start with the equation M dS = du + (Œ) dv - Ž (#) an, dU du+av-dN; j=1 Why doesn't the equation for the entropy of an ideal gas depend on the strength of the intermolecular forces for the gas?

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster. A. What is the work of expansion upon freezing? B. Is work done on the system or by the system?

I have a excitation/emission spectra of a quinine standard solution here, and I'm having trouble interpreting it. the red line is emission the blue line is excitation. i'm having trouble interpreting properly. just want to know if there is any evidence of raman or rayleigh peaks in the spectra.
