Question

Where does EAS take place next on this molecule? A B C D Please these compounds in order of increasing reactivity with nucleophiles. Place the least reactive first? D,B,C,A A,C,B,D D,C,B,A B,C,A,D what differences in the IR spectra of the reactant and product would be expected. The reactant would have a large, broad peak at -3300 and 1700 cm-1 in its IR spectrum, and only the peak at - 3300 cm-1 would be absent in the product's IR spectrum. The reactant would have a large broad peak at -1700 cm^-1 in its IR spectrum, which would be absent in the product's IR spectrum The reactant would have a large, broad peak at -3300 cm-1 in its IR spectrum, which would be absent in the product's IR spectrum. Impossible to distinguish by IR.

Explanation / Answer

1) No B, both are ortho para directing groups. due to the bulky group, the electrophile prefer to attack B rather than C and D.

2) Correct

3) Correct, the alcohol gives a broad peak aroung 3500 in IR spectrum but there wont be any peak at 1700.
