What is the total number of distinct 13C NMR signals that may be observed for the product, methyl-3-nitrobenzoate, and for the r
eactant, methylbenzoate?What is the total number of distinct 13C NMR signals that may be observed for the product, methyl-3-nitrobenzoate, and for the reactant, methylbenzoate?
1 answer:
Answer:
See explaination
Explanation:
methyl-3-nitrobenzoate = 3-NO2-C6H4-COOCH3
Singlet at 4 ppm = CH3 from ester (COOCH3)
Triplet at 7.6 ppm = Aromatic, H5 proton
Doublet at 8.2 ppm - Aromatic, H4 and H6 protons
Singlet at 8.8 ppm - Aromatic, H2 proton

Answer:
Titration
Explanation:
The best technique which can be used to determine the number of moles of the HCl in the sample is titration.
The given amount of HCl solution must be titrated with known concentration of the base like NaOH.
The volume of NaOH required must be noted also.
According to the reaction,
At equivalence point
Moles of = Moles of
Considering:-
Moles of
Thus, in this way, moles of HCl can be determined.
