1 1
2 2
3 3
4 4
Explanation:
No. of chiral center in an aldoheptoses when terminal groups are different. No. of isomers \({\mathrm{=2^{5}=32}}\) \({\mathrm{X=\dfrac{32}{8}=4}}\)
(A - Q) Glucose \({\mathrm{\xrightarrow[\Delta]{\mathrm{NaHCO}_{3}}}}\) No reaction (B - S) Glucose \({\mathrm{\xrightarrow{\mathrm{HNO}_{3}}}}\) Saccharic acid (C - R) Glucose \({\mathrm{\xrightarrow[\Delta]{\mathrm{HI}} \mathrm{n}}}\)-Hexane (D - P) Glucose \({\mathrm{\xrightarrow[\text { Water }]{\mathrm{Br}_{2}}}}\) Gluconic acid So, the correct option is (3).
