Carbohydrates typically give a positive reaction to the Molisch test. This is because the Molisch reagent reacts with the carbohydrates to form a purple complex, indicating the presence of sugar molecules in the solution.
Molisch's test is known as a group test because it can detect the presence of any carbohydrate in a sample, regardless of the specific type of carbohydrate. This test relies on detecting the presence of reducing sugars, which are a common feature of most carbohydrates, making it a broad test for the presence of carbohydrates in general.

of course she can
Blood group O Positive is considered the universal donor because it lacks A or B antigens on the surface of red blood cells. This means it can be transfused to individuals with any ABO blood type without causing an immune reaction. Additionally, the presence of the Rh antigen (Positive) ensures compatibility with Rh-positive recipients.
The reaction for the modified Fehling's test involves the oxidation of an aldehyde to a carboxylic acid in the presence of copper(II) ions. This reaction results in the formation of a brick-red precipitate of copper(I) oxide, which indicates a positive test for the presence of an aldehyde group.

No, 2-pentanone would not give a positive reaction to the Iodoform test. The Iodoform test is specific for methyl ketones (ketones with a methyl group adjacent to the carbonyl), and 2-pentanone does not have this structure. Instead, it has a butyl group adjacent to the carbonyl, which does not lead to the formation of iodoform.
AB positive / A positive / B positive
is A positive blood group and AA blood group the same
no
In the given reaction, the SO3H group is activating.
Yes

what is a gf blood group? And what is the question?
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
No, an O-group parent cannot have an AB-group child at all.
Yes, if the mother is group A or group O.
