(b)
Interpretation:
The structure of compound that has molecular formula
Concept introduction:
Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment around the hydrogen atom.

- How do you determine pKa values from the molecules?arrow_forwardPhenol, C6H5OH, is an acidic organic compound for which K₂ = 1.3 x 10-10. The structure of phenol is a benzene ring with an -OH replacing a hydrogen atom on one of its six carbon atoms. Because phenol has this -OH group, you might think that the -OH would ionize and make phenol a base. Actually, the O-H bond is very weak and phenol acts as an acid by ionizing the H* ion. What is the pH of a 0.47 M solution of phenol in water? pH=ễarrow_forward4. A student has prepared 0.05 M solution of CH3-C=CH and has added to it 0.05 M solution of potassium tert-butoxide (K" O-C(CH3)3). (i) Write the equation for the acid-base reaction that might occur. (ii) With curved arrows track the movements of electron pairs. (iii) Assign Base, Acid, Conjugate acid for the base, Conjugate base for the acid. (iv) Calculate the percentage of deprotonated methyl acetylene taking into account that pKa of the conjugate acid of potassium tert-butoxide equals 18 and pKa of methyl acetylene equals 24.arrow_forward
