Which one of the following statements is nottrue regarding (+) Lactose...
Explanation:

Statement c: (+) Lactose is a reducing sugar and does not exhibit mutarotation.
- (+) Lactose is indeed a reducing sugar because it has a free anomeric carbon in the glucose molecule that can reduce other compounds.
- Mutarotation is the interconversion of α and β anomers of a compound in solution. (+) Lactose can undergo mutarotation due to the presence of free anomeric carbon in glucose.
- Therefore, statement c is not true as (+) Lactose does exhibit mutarotation.
In summary, the correct answer is option 'C' because (+) Lactose is a reducing sugar and does exhibit mutarotation.

Read the passage given below and answer the following questions:Benzene ring in aniline is highly activated. This is due to the sharing of lone pair of nitrogen with the ring which results in increase in the electron density on the ring and hence facilitates the electrophilic attack. The substitution mainly takes place at ortho and para positions because electron density is more at ortho and para positions. On reaction with aqueous bromine all the ortho and para positions get substituted resulting in the formation of 2,4,6-tribromoaniline. To get a monobromo compound, the amino group is acetylated before bromination. After bromination, the bromoacetanilide is acid hydrolysed to give the desired halogenated amine.In the following questions, a statement of assertion followed by a statement of reason is given.
