Give the reaction of the following `:`
`i.`
`ii.` `2-`Bromo butane `+ C_(2)H_(5)Ona(` three products `)`

Explanation

`i.`
`ii.`
`iii.`
`iv.` Add `H^(o+)` to each `CB` and find acidic acid and then reverse them for the basic order.
(Acid `: HOH, ROH, RCOOH, HCN, HNO_(3))`
Acidic order : `HNO_(3) gt RCOOH gt HCN lt H_(2)O lt ROH`
Basic order :
`NO_(3)^(Θ) lt RCOO^(Θ) lt CN^(Θ) lt O^(Θ)H lt RO^(Θ)`
