Passage I
A and B are two structural isomers with their molecular formula C7H14O and both gives-off effervescence on heating with Na-metal. However, neither A nor B decolourise brown colour of Br2-H2O. Treating either A or B with hot conc, sulphuric acid solution results in the form ation of the same compound C (C7H12). C on treatment with O3 followed by Zn-H2O gives D (C7H12O2). D gives E (C7H16O2) on treatm ent with NaBH4. E has only one methyl group and forms yellow ppt with I2/KOH. Also, A gives delayed turbidity on treatment with conc. HCI/ZnCI2 while B gives immediate turbidity on similar treatment.
Q. 
Which of the following statement regarding A and B is incorrect?
  • a)
    Only A will change the colour of dichromate solution not B
  • b)
    C on reaction with (CH3COO)2Hg/H2O followed by NaBH4 gives B
  • c)
    C on treatment with B2H6/H2O2 followed by alkaline work-up gives A
  • d)
    Treating either A or 8 with SOCI2 followed by the reduction with LiAIH4 results in the formation of same product
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Passage IA and B are two structural isomers with their molecular formu...
Both A and B are alcohols with one degree of unsaturation but none of them decolourise Br2 - H2O solution,hence they are cyclic.

E has only one methyl group and gives iodoform test hence, E may be : 


A has a chiral carbon but B does not.
B is a tertiary alcohol, does not react with SOCI2.

Incorrect Statement regarding A and B

Statement B: C on reaction with (CH3COO)2Hg/H2O followed by NaBH4 gives B

Explanation:
- The given statement is incorrect because the reaction described actually leads to the formation of compound D (C7H12O2) from compound C (C7H12), not B.
- The reaction involves the conversion of C to D through the intermediate compound formed by the reaction with (CH3COO)2Hg/H2O followed by NaBH4.
- Hence, the statement B does not correctly represent the reaction pathway of C to form D.
