Given:
The compound(s), which on reaction with HNO3 will give the product having a degree of rotation, [α]D = –52.7º is(are);
The compound(s), which on reaction with HNO3 will give the product having a degree of rotation, [α]D = –52.7º is(are);
The Correct Option is C, D
Solution and Explanation
|
The enantiomer of (P) will have –52.7º rotation. So the reactant must be an isomer of D-glucose which can given the mirror image of (P)

- Coordinate Geometry
The center of a disk of radius $ r $ and mass $ m $ is attached to a spring of spring constant $ k $, inside a ring of radius $ R>r $ as shown in the figure. The other end of the spring is attached on the periphery of the ring. Both the ring and the disk are in the same vertical plane. The disk can only roll along the inside periphery of the ring, without slipping. The spring can only be stretched or compressed along the periphery of the ring, following Hooke’s law. In equilibrium, the disk is at the bottom of the ring. Assuming small displacement of the disc, the time period of oscillation of center of mass of the disk is written as $ T = \frac{2\pi}{\omega} $. The correct expression for $ \omega $ is ( $ g $ is the acceleration due to gravity):

Glucose
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.
