Hi, I need help on this question. Thank you.

Consider the sequence of reactions below. In this sequence of reactions, an unsaturated ketone is treated with a Gilman reagent, followed by treatment with an aqueous base. The base allows a rapid equilibration to take place, producing the more stable stereoisomer of the product. 1. Et,CuLi 2. Equilibration with base For this process: show both stereoisomeric products, explain which is more stable, and explain why aqueous base allows equilibration between the stereoisomers.

Assume ortho and para isomers can be separated. 0₂N- i) ii) (H3C)3C CI NH₂ -COOH C(CH3)3 CH3 NHCOCH3 iii) CH₂CH3 d) With the aid of resonance structures explain why electrophilic substitution of benzaldehyde takes place preferentially at the meta position.
Provide a reasonable stepwise mechanism for the following transformation. Show the structure of any intermediates and use the arrow formalism to account for electron flow. Draw the structure of the regioisomer that might form and suggest a reason why it would not be produced.

The reaction between singlet oxygen and limonene (below) is often used to characterize the behaviour of singlet oxygen as an electrophile rather than an initiator for a free radical mechanism. HOO Limonene Scheme 1 (a) Since singlet oxygen is a high energy state, the formation of a diradical seems plausible: 0=0* Propose a sequence of steps for this diradical reacting with limonene and explain why the major product, which is obtained (Scheme 1), does not support this reaction mechanism
A compound with the molecular formula, C,,H0 was treated with Wolff-Kishner reagent and the product, C,,H,, was formed. Treatment of this compound with hot KMNO,, generated C,H,0, as one of the products. When this product was heated with 10° 12 4 AIPO, at 7000C, an anhydrous product was formed with the formula, C3H,O,. Determine the structures of all the reactants and products.
