Shivam Khanna answered |
The g-value in ESR (electron spin resonance) spectroscopy refers to the spectroscopic splitting factor, which is a dimensionless constant that describes the relationship between the magnetic field and the energy difference between the two spin states of an electron. In the case of organic radicals, the g-value generally ranges from 1.99 to 2.01.

Palak Singh answered |
Angular momentum is a property of a rotating object and is defined as the product of the moment of inertia and the angular velocity. In the case of a particle moving on a ring, the moment of inertia is given by the product of the mass and the square of the distance from the axis of rotation. The angular velocity is the rate at which the particle is moving around the ring.

Saanvi Roy answered |
Explanation:
In a cubic crystal, the planes [100], [010], and [001] are all mutually perpendicular to each other and intersect at right angles. This is because in a cubic crystal, the lattice points are arranged in a regular, repeating pattern along three mutually perpendicular axes.
Equally inclined planes:

Akshat Saini answered |
Explanation:
Statement a: When Cl2 is added to KI solution containing chloroform, chloroform turns violet.
This statement is incorrect. When Cl2 is added to KI solution containing chloroform, the chloroform does not turn violet. Instead, it forms a layer at the bottom of the mixture due to its higher density compared to water. This is because chloroform is immis... more

Imidazole has a pKa = 7 with respect to its conjugate acid. Which N is protonated in this conjugate acid and why?
- a) N1 because imidazole is an aromatic heterocycle where n = 1 as per Huckel’s rule.
- b) N1 is protonated because it is sp3 hybridized.
- c) N3 is protonated because it is sp2 hybridized.
- d)N1 is protonated because the lone pair is part of the aromatic pi system

The lone pair of N1 are participating in aromaticity so they are not available to donate
& lone pair of N5 are free to donate so N5 will be protonated
& lone pair of N5 are free to donate so N5 will be protonated

Organic Chemistry is a branch of chemistry that deals with the study of the structure, properties, composition, reactions, and synthesis of organic compounds, which contain carbon atoms. Carbon is unique in its ability to form covalent bonds with other carbon atoms, allowing for the formation of a wide variety of compounds with diverse structures and properties.
