Inductive Effect: The polarization of σ bond due to electron withdrawing or electron donating effect of adjacent groups or atoms is called inductive effect. Salient features of inductive effect: It arises due to electronegativity difference between two atoms forming a sigma bond. It is transmitted through the sigma bonds. The magnitude of inductive effect decreases while moving Read more about Fundamental Concepts of Inorganic Reaction Mechanisms II[…]

When a rigid body rotates about an axis, it possesses kinetic energy. All the kinetic energy of a rotating body is rotational kinetic energy (Kr). Let us now find the kinetic energy of a rotating body. The particle of mass m1 follows a circular path of radius r1. The magnitude of the linear or tangential Read more about Moment of Interia[…]

Condition for the lines to be coincident: The lines are coincident if the angle between them is zero. Thus, lines are coincident. ⇒ θ = 0 ⇒ tanθ = 0 ⇒ . ⇒ h2 – ab = 0 ⇒ h2 = ab Hence, the lines represented by ax2 + 2hxy + by2 = 0 are Read more about Lines to be Coincident, Perpendicular & Equation of Second Degree & Bisectors[…]

Types of Bond cleavage Homolytic cleavage: Homolytic fission is where each atom of the bond keeps an electron each resulting in species called free radicals. R−X→R∙+X∙ Homolytic cleavage occurs generally in the gas phase or in solution in non-polar Solvents and is catalyzed by ultraviolet light or high temperature of or by radical initiators such as Read more about Fundamental Concepts of Inorganic Reaction Mechanisms I[…]

The Kelvin temperature scale is also known as thermodynamic scale. The S.I. unit of temperature is kelvin and is defined as (1/273.16) of the temperature of the triple point of water. The triple point of water is that point on a P-T diagram where the three phases of water, the solid, the liquid and the Read more about Scales of Temperature[…]
