Difference between Benzyne and Benzyl
Benzyne | Benzyl | |
|---|---|---|
Identification | Benzyne is identified as a triple bond between two adjacent carbon atoms in a benzene ring. Root- Benzyne (like the triple bond of alkyne) |
Organic Chemistry

Learning Objective: To study Vander Waals Keesom's force, interactions, and strength.
Skill Level – Intermediate
Prerequisites:
Calculate empirical formula - MgSO4.7H2O
A salt containing water of crystallization gave the following percentage composition :
Mg = 9.76 ; S = 13.01 ; O = 26.01 and H2O = 51.22.
Is a metallic bond - covalent or ionic in nature?
In ionic compounds, a metal atom loses an electron, forms a cation, and another nonmetal atom gains it, creating an anion. Thus, there is a complete transfer of electrons between the two atoms. The ions are part of a fixed crystal lattice and immobile in the solid state. For example, NaCl, KBr.
Calculation for the number of electrons that flow through a metallic wire (using log table) -Electrochemistry
Question: How many electrons flow through a metallic wire if a current of 0.5 A is passed for 2 hours? (Given: 1F= 96,500 C/mol)
Solution:
Differences between Organic and Inorganic compounds
Organic Compounds | Inorganic Compounds | |
|---|---|---|
Based on source (Older definition) | Compounds isolated directly or indirectly from living organisms such as plants and animals were earlier called Organic compounds (based on the Vital Force Theory). |
Difference Between Valence and Core electrons
Valence Electrons | Core Electrons |
|---|---|
Valence Electrons are farthest away from the nucleus at the outermost shell. This increase in the distance from the nucleus weakens the attractive nuclear interactions raising its energies. | The core electrons are the those present closer to the nucleus. Their attractive interactions with the nucleus are stronger, which lowers their energy and contributes to stability. |
