Given below are two statements :
Statement I: Maltose has two\(α-D-glucose\) units linked at \(C_1\) and \(C_4\) and is a reducing sugar.
Statement II: Maltose has two monosaccharides :
\(α-D-glucose\) and \(β-D-glucose\) linked at \(C_1\) and \(C_6\) and it is a non-reducing sugar.
In the light of the above statements, choose the correct answer from the options given below.
Statement I: Maltose has two\(α-D-glucose\) units linked at \(C_1\) and \(C_4\) and is a reducing sugar.
Statement II: Maltose has two monosaccharides :
\(α-D-glucose\) and \(β-D-glucose\) linked at \(C_1\) and \(C_6\) and it is a non-reducing sugar.
In the light of the above statements, choose the correct answer from the options given below.
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
The Correct Option is C
Solution and Explanation
Maltose is composed of two \(α-D-glucose\) units in which \(C_1\) of one glucose unit and \(C_4\) of second glucose unit are linked.
\(Hence,\) the correct option is (C): Statement I is true but Statement II is false

Concepts Used:
Structure of Organic Compounds
The three structural formulas – complete structure, condensed structure, and bond line structural formulas are explained below:
Complete Structural Formula-
The Lewis dot structure is considered as the complete structural formula. In Lewis structure, the covalent bonds in the compound are denoted by a dash (―). This helps to emphasize the number of bonds formed by the electrons. Every single bond, a double bond, and a triple bond are represented by one dash, double dash, and triple dash respectively. It illustrates every single bond formed between every atom in the compound, thus called complete structural formula.
Condensed Structural Formula-
Since complete structural formula consumes much time and space to represent the structure, we can condense them. This is the condensed structural formula, where replacing some dashes/bonds by a number of identical groups attached to an atom by a subscript.
Bond Line Structural Formula-
A bond lines structural formula is another way of structural representation of organic compounds. Here, every bond is represented as a line in a zigzag manner. If not specified, every terminal is assumed to be a methyl (-CH3) group.
