Match items of Row I with those of Row II.

Row I:

(P)
Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

(Q)
Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

(R)
Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

(S)
Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

Row II:

(i) α‐D‐(—)\alpha ‐ D ‐ ( — ) Fructofuranose.

(ii) β‐D‐(—)\beta ‐ D ‐ ( — ) Fructofuranose.

(iii) α‐D‐(‐)\alpha ‐ D ‐ ( ‐ ) Glucopyranose.

(iv) β‐D‐(‐)\beta ‐ D ‐ ( ‐ ) Glucopyranose.

Correct match is

Options

  1. AP→iv, Q→iii, R→i, S→ii
  2. BP→i, Q→ii, R→iii, S→iv
  3. CP→iii, Q→iv, R→ii, S→i
  4. DP→iii, Q→iv, R→i, S→ii

Correct answer

D. P→iii, Q→iv, R→i, S→ii

Step-by-step solution

Structure

Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

Represents α‐D‐(+)\alpha ‐ D ‐ ( + ) Glucopyranose

Structure

Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

Represents β‐D‐(+)\beta ‐ D ‐ ( + ) Glucopyranose

Structure

Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

Represents α‐D‐(−)\alpha ‐ D ‐ ( - ) Fructofuranose

Structure

Match items of Row I with those of Row II. Row I: (P) (Q) (R) (S) Row II: (i) α ‐ D ‐ ( — ) Fructofuranose. (ii) β ‐ D

Represents β‐D‐(−)\beta ‐ D ‐ ( - ) Fructofuranose

So, the correct option is D
