Question
Draw the structure of Compound A. Explain the reason for using aq. HCI solution in the work-up of the above reaction. Include a balanced chemical equation in your answer. Based on your answers to Q2 and Q3, estimate the inter-ring dihedral angle of Compound A. Write down your estimated value and then calculate the dihedral angle of Compound A Comment upon how well your initial estimation of the dihedral angle compares to the calculated value, and compare the calculated value to those obtained for biphenyl, 2-methylbiphenyl, and 2,6-dimethylbiphenyl. What does the calculated inter-ring dihedral angle of Compound A tell you about the relative steric demand of an F-atom compared to a CH3 group in biaryl compounds?Explanation / Answer
For compound D, the dihedral angle is estimated as 1800(anti) because the two phenyl groups are interlinked nearly by 900 and also the -COOH and -F groups attached to one phenyl group is exactly opposite with other phenyl group. Generally in conformations of this compound is called as anti form.
