a)
Interpretation:
The reason why diluted tequila is extracted by four times with dichloromethane rather than one time with a higher volume has to be explained.

b)
Interpretation:
The reason for the usage of on-column injection has to be explained.
Concept Introduction:
On-Column injection:
On-column injection is the best method for quantitative analysis for compounds that are thermally sensitive. It is low resolution technique and doesn’t support for columns with diameters less than 0.2 mm. On-column injection can be used to handle solutions that dilute and concentration in solution both in large and small volumes.

Interpretation:
The reason for the usage of poly (ethylene glycol) column has to be explained.
To explain the usage of poly (ethylene glycol) column
d)
Interpretation:
The phase ratio
Concept Introduction:
Phase ratio
The volume of mobile phase divided by the volume of the stationary phase is called as dimensionless phase ratio. The phase ratio is calculated as,

- CH3 CH H3C CH3 H OH H3C- -OCH2CH3 H3C H -OCH3 For each of the above compounds, do the following: 1. List the wave numbers of all the IR bands in the 1350-4000 cm-1 region. For each one, state what bond or group it represents. 2. Label equivalent sets of protons with lower-case letters. Then, for each 1H NMR signal, give the 8 value, the type of splitting (singlet, doublet etc.), and the number protons it represents. of letter δ value splitting # of protons 3. Redraw the compound and label equivalent sets of carbons with lower-case letters. Then for each set of carbons give the 5 value and # of carbons it represents. letter δ value # of carbonsarrow_forwardDraw the correct ionic form(s) of arginine at the pKa and PI in your titration curve.

If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.arrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forwardWhat should be use to complete the reaction?
