| Assertion : Glucose when treated with \[C{{H}_{3}}OH\] in presence of dry HCl gas gives \[\alpha \]-and \[\beta \]-methyl glucosides. |
| Reason : Glucose reacts with phenyl hydrazine to form crystalline osazone. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: B
Solution :
Because of the ring structure \[{{C}_{1}}\], in glucose becomes chiral and hence glucose exists in two stereoisomeric forms, i.e., \[\alpha \]- and \[\beta \], corresponding to each stereoisomeric form glucose forms two methyl glucosides, i..e., \[\alpha \]- and \[\beta \]-methyl glucosides.
