The correct functional group Xandthereagent/reactionconditionsX and the reagent/reaction conditionsYinthefollowingschemesarein the following schemes are\mathrm{X}-(CH2)4−X\left(\mathrm{CH}_2\right)_4-X The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X

Options

  1. AX=COOCH3,Y=H2/Ni/X=\mathrm{COOCH}_3, Y=\mathrm{H}_2 / \mathrm{Ni} / heat
  2. BX=CONH2,Y=H2/Ni/X=\mathrm{CONH}_2, Y=\mathrm{H}_2 / \mathrm{Ni} / heat
  3. CX=CONH2,Y=Br2/NaOHX=\mathrm{CONH}_2, \quad Y=\mathrm{Br}_2 / \mathrm{NaOH}
  4. DX=CN,Y=H2/Ni/X=\mathrm{CN}, Y=\mathrm{H}_2 / \mathrm{Ni} / heat

Correct answer

C. X=CONH2,Y=Br2/NaOHX=\mathrm{CONH}_2, \quad Y=\mathrm{Br}_2 / \mathrm{NaOH}

Step-by-step solution

(a) The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X
(b)The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X
(c)The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X
(d)The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X
 In author’s opinion (a) and (b) should also be the answer. \text{ In author's opinion (a) and (b) should also be the answer. }The correct functional group X and the reagent/reaction conditions Y in the following schemes are X- (CH_2)_4-X
