(i) When D-glucose is heated with HI for a long time, n-hexane is formed.

(ii) When D-glucose is treated with Br2 water, D- gluconic acid is produced.

(iii) On being treated with HNO3, D-glucose get oxidised to give saccharic acid.

Write IUPAC names of the following compounds and classify them into primary, secondary and tertiary amines.
(i) (CH3 )2CHNH2 (ii) CH3 (CH2 )2NH2 (iii) CH3NHCH(CH3 )2
(iv) (CH3 )3CNH2 (v) C6H5NHCH3 (vi) (CH3CH2 )2NCH3 (vii) m–BrC6H4NH2
Give one chemical test to distinguish between the following pairs of compounds.
(i) Methylamine and dimethylamine
(ii) Secondary and tertiary amines
(iii) Ethylamine and aniline
(iv) Aniline and benzylamine
(v) Aniline and N-methylaniline
Account for the following:
(i) pKb of aniline is more than that of methylamine.
(ii) Ethylamine is soluble in water whereas aniline is not.
(iii) Methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide.
(iv) Although amino group is o– and p– directing in aromatic electrophilic substitution reactions, aniline on nitration gives a substantial amount of m-nitroaniline.
(v) Aniline does not undergo Friedel-Crafts reaction.
(vi) Diazonium salts of aromatic amines are more stable than those of aliphatic amines. (vii) Gabriel phthalimide synthesis is preferred for synthesising primary amines.
Glucose is a simple sugar, also known as dextrose, that is a primary source of energy for living organisms. It is a monosaccharide, meaning it consists of a single sugar unit, and is chemically classified as an aldohexose, which means it has six carbon atoms and an aldehyde functional group.
Glucose is produced by plants through the process of photosynthesis, where it is synthesized from carbon dioxide and water using energy from sunlight. It is also produced in the human body through the breakdown of complex carbohydrates, such as starch and glycogen, in the process of digestion.
Glucose is transported throughout the body via the bloodstream and taken up by cells where it is metabolized to produce energy in the form of ATP. Excess glucose can be stored in the liver and muscles as glycogen for later use.

Glucose is an important component of many foods, such as fruits, honey, and sweetened beverages. It is also used as a sweetener in the food industry and as a medical treatment for hypoglycemia, a condition characterized by low blood glucose levels.
Measurement of glucose levels in the blood is an important diagnostic tool for monitoring and managing diabetes, a chronic metabolic disorder characterized by high blood glucose levels. Glucose testing can be done using a variety of methods, such as fingerstick testing and continuous glucose monitoring.
