(b)
Interpretation: Reactants required to prepare the given enamine has to be identified.
Concept introduction:
Enamine reaction:
Carbonyl compound (ketone or aldehyde) reaction with secondary amine in the presence of acid which gives enamine.
An enamine is a compound where the lone pair of electrons in the nitrogen atom of
It is formed by the reaction of a ketone or aldehyde and a secondary amine under acidic conditions with the elimination of water molecule.
Retro synthesis: It is a technique of planning an organic synthesis by the reverse approach. In this technique, the starting materials are obtained by cleaving the target molecule into logical synthons. Synthons are precursor fragments of the target compound when it is cleaved. Depending on the stability, the synthons are classified as logical and illogical synthons. Logical synthons are highly stable precursor fragments, and illogical synthons are less stable precursor fragments of the target compound.

- 4. Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forwardSteps and explanation pleasearrow_forward

Use the diffusion model from lecture that showed the likelihood of mixing occurring in a lattice model with eight lattice sites: Case Left Right A B C Permeable Barrier → and show that with 2V lattice sites on each side of the permeable barrier and a total of 2V white particles and 2V black particles, that perfect de-mixing (all one color on each side of the barrier) becomes increasingly unlikely as V increases.arrow_forward46. Consider an ideal gas that occupies 2.50 dm³ at a pressure of 3.00 bar. If the gas is compressed isothermally at a constant external pressure so that the final volume is 0.500 dm³, calculate the smallest value Rest can have.
