When a man travels from earth to space, the mass of the person, defined as the amount energy a matter has remains constant. However, when he moves to space, gravity decreases until such time that there is no gravity that acts on the person. Weight thus changes or decreases until the point of state called weightlessness.

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5

djyliett [7]

Question:

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5 hydroxyl group?

a. disaccharide

b. carboxylic acid

c. hemiacetal

d. ester

e. stereoisomer

Answer:

hemiacetal forms in the intramolecular reaction between the aldehyde portion of the glucose molecule and its C-5 hydroxyl group

Explanation:

It is an alcohol also an ether that has been attached to the carbon molecule. Here the hydrogen has occupied the fourth bonding position. This hemiacetal has been derived from the aldehyde. Hence, hemiketal being an alcohol as well as ether has been attached to the same carbon and also to the two other carbon.
