Compound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O...

Compound A,C5H10O5A, {C}_{5}{H}_{10}{O}_{5}, given a tetraacetate with AC2O{AC}_{2}O and oxidation of AA with Br2−H2O{Br}_{2} - {H}_{2}O gives an acid, C5H10O6{C}_{5}{H}_{10}{O}_{6}. Reduction of AA with HIHI gives isopentane. The possible structure of AA is :Compound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives anCompound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives anCompound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives anCompound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives anCompound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives an

Options

  1. AThe correct sequence of reagents for the preparation of Q and R is:
  2. BThe correct sequence of reagents for the preparation of Q and R is:
  3. CThe correct sequence of reagents for the preparation of Q and R is:
  4. DThe correct sequence of reagents for the preparation of Q and R is:

Correct answer

C. The correct sequence of reagents for the preparation of Q and R is:

Step-by-step solution

Formation of tetraacetate with acetic anhydride means compound A has four −OH- OH linkage. Reduction of A with HIHI gives isopentane i.e. molecule contains five carbon atoms.

Compound A, C _ 5 H _ 10 O _ 5 , given a tetraacetate with AC _ 2 O and oxidation of A with Br _ 2 - H _ 2 O gives an

So, C is the correct option
