Question

Need help with 11-13 What is the length in angstroms (A, 10^-10m) of the bound between the carbanion and carbonyl carbons of the following compound? Knowing that suffur is just below oxygen in the Periodic Table, which compound would react third fastest with tert-butyl chloride and AJCL_2? Which position would be most substituted if reached with CH_3Cl/AlCl_3? -16, Starting with benzene, match each reaction sequence to a major product below. Assume any necessary between steps, which are separated by commas. Answers may be repeated. Cl_2/AlCl_2, NaNH_2, cold NaNO_2/HCl, CuOH, HNO_3/H_2SO_4, use the minor product from previous step, H_2/pd, NaNO

Explanation / Answer

11) it is in between single and ouble bond character   1.4   (because of resonance)

13) position e is more favourable

because S=O   act as electron withdrawing group so electrophilic substitution is less favour but due to presence of -OR group it activate the ring to which it attached. it that again it is favoured at ortho (e)   not at meta (d).

so position e is more favoured
