Concept explainers
(a)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction: If the conformer shows the minimum steric hindrance of the substituent and minimum torsional strain then that conformer is in stable form.
(b)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction: Trans-isomer has opposite attachment of all groups on the ring.
(c)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:All groups are situated in one side, it is cis-isomer. Stability is defined in terms of axial interactions.
(d)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:In trans-isomer all groups are attached in opposite side of the ring.
(e)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:When groups are on one side then that isomer is cis-isomer.
(f)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:Trans-isomer consist all different groups on the opposite side of the ring.
(g)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:If all groups of the ring are attached on same side then that isomer is cis-isomer.
(h)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:If the groups are attached on the same side then that isomer is cis-isomer.
(i)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:In cis-isomer the all different groups are situated on the same side of the ring.
(j)
Interpretation: The isomer type needs to be determined and the stable conformation needs to be drawn.
Concept Introduction:Trans-isomers have the different groups on the opposite side of the ring.

- I need help with the followingarrow_forwardFor Raman spectroscopy/imaging, which statement is not true regarding its disadvantages? a) Limited spatial resolution. b) Short integration time. c) A one-dimensional technique. d) Weak signal, only 1 in 108 incident photons is Raman scattered. e) Fluorescence interference.arrow_forwardUsing a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. 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.
