Q4. Identify the most stable alkyne in the following molecules: C Page< 2 > of 40 Q5. Use arrow-pushing mechanism for the following reactions. Identify if they are SN1/SN2; E1/E2 reactions: Na CN Br 1. DMSO tBuOK 2. CI tBuOH 3. Br CH3OH 4. CI 3 W E R Acetone/H₂O heat 96 5 6 prt sc home end insert F10 F11 & 8 9 Y U S D F G H 0 P

Pls help ASAP on both.

The 1 & 2  answer option refers to (2R, 3R) and (2S,3S).

Give a clear handwritten answer..Give the major product given below reactions...

1. .CI HC C: Li HC CH LICI 2. -CH3 OH Aqueous HO-S- -CH3 acetone g = SN1 Nucleophilic substitution Electrophilic a = Proton transfer addition h = SN2 Nucleophilic substitution b = Lewis acid/base e = El Elimination c = Radical chain f= E2 Elimination substitution Identify the mechanism by which each of the reactions above proceeds from the mechanisms listed. Use the letters a - i for your answers. among 1. 2.

Can anyone explain how to solve this?
