Q. Identify the set of reagent / reaction conditions X and Y in the following set of transformations. $C H_{3} - C H_{2} - C H_{2} B r X Product Y$ $C H_{3} - B r ∣ C H - C H_{3}$

X = dilute aqueous $N a O H,$ $20^{\circ} C;$ Y = HBr/acetic acid, $20^{\circ} C$

X = concentrated alcoholic $N a O H,$ $80^{\circ} C;$ Y = HBr/acetic acid, $20^{\circ} C$

X = dilute aqueous $N a O H,$ 20?C; Y = $B r_{2} / C H C l_{3}, 0^{\circ} C$

X = concentrated alcoholic $N a O H,$ $80^{\circ} C;$ Y = $B r_{2} / C H C l_{3}, 0^{\circ} C$

X = dilute aqueous NaOH, 20∘C; Y = HBr/acetic acid, 20∘C

X = concentrated alcoholic NaOH, 80∘C; Y = HBr/acetic acid, 20∘C

X = dilute aqueous NaOH, 20?C; Y = Br2​/CHCl3​,0∘C

X = concentrated alcoholic NaOH, 80∘C; Y = Br2​/CHCl3​,0∘C
