Haber Process for Ammonia Manufacturing The Haber process is used to synthesise ammonia (NH₃) from nitrogen and hydrogen gases. It’s one of the most important chemical processes, which enabling the production of fertilizers. Chemical Reaction: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) (ΔH = -92 kJ/mol) The combination of atmospheric nitrogen with hydrogen to produce ammonia. […]
Catalytic properties of d – block elements: Catalytic properties of d- block elements are mainly due to the following reasons: 1.The presence of vacant d orbitals. 2.They have the ability to exhibit variable 3.They have a tendency to form complex compounds. Examples: Platinum (Pt): It is used as a catalyst in the manufacture of sulphuric […]
Chain isomerism : The structural isomerism in which compounds have the same molecular formula but differ in the arrangement of their carbon chains. This difference may be due to straight-chain or branched-chain structures.The carbon atoms are connected in a straight or branched way. Examples: 1.Butane (C₄H₁₀): n-Butane: CH₃–CH₂–CH₂–CH₃ (straight chain) and Isobutane: CH₃–CH(CH₃)–CH₃ (branched […]
ISOMERISM the phenomenon in which two or more compounds have the same molecular formula but differ in their physical and chemical properties.These compounds are known as isomers. TYPES OF ISOMERISM : Isomerism is broadly divided into two main categories: 1. Structural (constitutional) isomerism. 2. stereoisomerism. I. Structural Isomerism: Structural isomers have the same molecular […]
The System in which both matter and heat can exchange with surrounding is called open system. Ex: boiling of water in open vessel.
Thermodynamically there are 3 types of systems. 1.Open system 2.closed system 3.isolated system
Correct answer :(C)orbit The Bohr radius is defined as the distance between the nucleus and the outermost electron in hydrogen atom in its ground state. It represents the distance between the nucleus and electron in hydrogen’s ground state (n=1), It approximately equal to 0.529 Å. Information about orbit : orbit represents a fixed circular […]
Correct answer :(4) Keto – enol tautomerism: It is an equilibrium between an aldehyde or ketone and a structural isomer called, the enol form. When acetylene reacts with water in presence of mercuric sulphate and Sulphuric acid, it initially converts into Vinyl alcohol which is present in enol form. The scene all form of vinyl […]
Correct answer : (2). Diborane reacts with water to give boric acid and hydrogen. B₂H₆ + 6 H₂O → 2 H₃BO₃ + 6 H₂. Formula of Boric acid is H₃BO₃, (it also written as B(OH)₃). Orthoboric […]
correct answer:(2) Structure of Diborane: The formula of diborane is B2H6.. Diborane consists of two boran Atoms connected by a bridge made of two bridges hydrogen atoms. Terminal Hydrogen Atoms: Each boran atom is bonded to two terminal […]
