Complete the following reactions`:`
`i.` `CH_(2)=CH_(2)` `overset(EtONa+eTOH)rarr`
`ii.` `F_(2)C=CF_(2)overset (EtONa+EtOH)rarr`

Text Solution

Verified by Experts

`i.` No reactions, Nucleophiles `(EtO^(Θ))` do not add to alkenes because they are repelled by the `pi bar(e)s` of the alkenes.
`ii.` The `EWG(bar(e)-` withdrawing groups) such as `F` atoms are attached to the `(C=C)` because they reduce the `bar(e)` density of the `pi-` bond and stabilisie th eintermediat carbonions.
