(a)
Interpretation:
The stereoisomer that would be formed in greatest yield in E2 reaction from the given alkyl halide has to be indicated.
Concept Introduction:
Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both base and substituents in the reaction) mechanism.
Elimination reaction of an alkyl halide results in the formation of an
Relative relativities of alkyl halide in an E2 reaction are
If the product obtained after E2 reaction has both E and Z stereoisomers, then E-isomer is the major product.
If the two largest groups in a molecule are in same side of the double bond, then it is called as Z-isomer.
If the two largest groups in a molecule are in opposite side of the double bond, then it is called as E-isomer.

Elimination reaction of an alkyl halide results in the formation of an alkene.
Zaitsev’s rule: In elimination reaction, when one hydrogen atom is removed from
Relative relativities of alkyl halide in an E2 reaction are
If the product obtained after E2 reaction has both E and Z stereoisomers, then E-isomer is the major product.

The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40. a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L) b) Calculate the molar absorptivity, a, of the 1645 cm-1 band c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c. (Please provide a full derivation of the equation for x from the equation for I). d) Calculate x for the 1645 cm-1 bandarrow_forward
- For CARS, which statement is not true regarding its advantages? a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging. b) Stronger signals than spontaneous Raman. c) Suffers from fluorescence interference, because CARS signal is at high frequency. d) Faster, more efficient imaging for real-time analysis. e) Higher resolution than spontaneous Raman microscopy.arrow_forwardDraw the major product of the Claisen condensation reaction between two molecules of this ester.
