IUPAC name for the molecule is to be written. Concept introduction: For a molecule that has more than one double bond or triple bond, the IUPAC name must indicate the number of double bonds or triple bonds present as well as their locations. To name the molecule with multiple double/triple bonds, establish the root as the longest carbon chain or the largest carbon ring that contains the greatest number of entire C=C or C ≡ C groups. Number the chain or ring so that each successive C=C or C ≡ C group is encountered the earliest. For each pair of C=C or C ≡ C atoms, identify the lower of the two locator numbers. Immediately before the ene or yne suffix, add the letter ‘a’ followed by the above set of locator numbers, and then add the prefix di, tri, etc. to specify the number of double or triple bonds. The substituents attached to the root are named in the alphabetical order.

Question

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.

Draw the major product of the Claisen condensation reaction between two molecules of this ester. Ignore inorganic byproducts. Incorrect, 5 attempts remaining 1. NaOCH3/CH3OH 2. Acidic workup Select to Draw O Incorrect, 5 attempts remaining The total number of carbons in the parent chain is incorrect. Review the reaction conditions including starting materials and/or intermediate structures and recount the number of carbon atoms in the parent chain of your structure. OK

Using 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 d) Calculate x for the 1645 cm-1 band
