Q.8 : Mechanism is not needed. Look up the use the use of the reagent nBu3SnH.
Double bond splits to form radical, at high temperature, 5 membered ring is thermodynamically more stable.

Which ones are left bro?

3,6,8,23 bro @KrishSharma

For 23 you can read this Antiperiplanar Relationships: The E2 Reaction and Cyclohexane Rings

WHY E 2 WHY NOT SN 2 ? bro @KrishSharma

The solvent is polar protic. Polar protic solvents hinder SN2 reactions, as they can hydrogen bond to nucleophiles and make them less effective in attacking the substrate. Ethanol is a polar protic solvent (though alcohols are only weakly acidic). It is commonly seen as a solvent/nucleophile (solvolysis) in SN1 reactions. @UnknowinglyAnonymous

i mean not sn2 or sn1 sorry but why not sn happening and here sn 2 will happen as main nucleophile is charged one other just stablizes the nucleophile

Remember that -ME groups attached to the carbon containing the leaving group increases rate of Sn2 greatly. ( -ME not -I)

Now 3 is done

In question 3, electron withdrawing effect increases Sn2

bro 4 th doubt hai … not 3 only see the ones i circled @Rudra_d
