QNEET-2024-Ch-121: NEET 2024 Chemistry - Class 11 NEET-2024-Ch-121 Solution: The alkane that can be oxidized to the corresponding alcohol by …

The alkane that can be oxidized to the corresponding alcohol by KMnO4KMnO_4 as per the equation is when: R1=H;R2=H;R3=HR_1=H; R_2=H; R_3=H R1=CH3;R2=CH3;R3=CH3R_1=CH_3; R_2=CH_3; R_3=CH_3 R1=CH3;R2=H;R3=HR_1=CH_3; R_2=H; R_3=H R1=CH3;R2=CH3;R3=HR_1=CH_3; R_2=CH_3; R_3=H

Multiple Choice Options

  • A R1=H;R2=H;R3=H\mathrm{R}_1=\mathrm{H} ; \mathrm{R}_2=\mathrm{H} ; \mathrm{R}_3=\mathrm{H} R 1 _ = H ; R 2 _ = H ; R 3 _ = H
  • B R1=CH3;R2=CH3;R3=CH3\mathrm{R}_1=\mathrm{CH}_3 ; \mathrm{R}_2=\mathrm{CH}_3 ; \mathrm{R}_3=\mathrm{CH}_3 R 1 _ = CH 3 _ ; R 2 _ = CH 3 _ ; R 3 _ = CH 3 _
  • C R1=CH3;R2=H;R3=H\mathrm{R}_1=\mathrm{CH}_3 ; \mathrm{R}_2=\mathrm{H} ; \mathrm{R}_3=\mathrm{H} R 1 _ = CH 3 _ ; R 2 _ = H ; R 3 _ = H
  • D R1=CH3;R2=CH3;R3=H\mathrm{R}_1=\mathrm{CH}_3 ; \mathrm{R}_2=\mathrm{CH}_3 ; \mathrm{R}_3=\mathrm{H} R 1 _ = CH 3 _ ; R 2 _ = CH 3 _ ; R 3 _ = H

Step-by-Step Verified Solution

Generally alkanes resist oxidation but alkane with tertiary H atom(s) can be oxidised to corresponding alcohols by KMnO 4 _ R 1 _ CH 3 R 2 _ CH 3 R 3 _ CH 3
