The funk. He was stuck on functional groups. Aldehydes and Ketones looked identical. Frustrated, he slammed the book shut. The corner of an old bus ticket fell out. On the back, in faded ink, was a note from his father: "Rohit, 1997: Haloalkanes = Alkane + Halogen. Just swap a H for X."
Here’s a (suitable for exams like SSC CGL, CHSL, CPO, GD, MTS, and state SSC exams).
Halogens (Fluorine, Chlorine, Bromine, Iodine) - highly reactive non-metals. chemistry notes ssc
Mercury is a liquid metal at room temperature; Bromine is a liquid non-metal. Ores: Memorize common ones: Iron: Hematite, Magnetite. Aluminium: Bauxite. Lead: Galena. Alloys: Brass: Copper + Zinc. Bronze: Copper + Tin. Steel: Iron + Carbon. 7. Carbon and Its Compounds
Carbon atoms arranged in a football shape (e.g., C60C sub 60 Buckminsterfullerene). Hydrocarbons Alkanes (Saturated): Single bonds only. General formula: (e.g., Methane CH4CH sub 4 , the main component of CNG and Biogas). The funk
Formed by neutralization reactions (Acid + Base → Salt + Water). pH Scale: Developed by Sorensen; ranges from 0 to 14. 5. Metals and Non-Metals Metals: Malleable, ductile, and good conductors. Mercury is the only metal liquid at room temperature. Non-Metals: Brittle and poor conductors. Bromine is the only non-metal liquid at room temperature. Graphite (Carbon) is a non-metal that conducts electricity. Alloys: Brass: Copper + Zinc Bronze: Copper + Tin Steel: Iron + Carbon Stainless Steel: Iron + Chromium + Nickel 6. Carbon and Its Compounds
By mastering these core concepts, you can easily secure full marks in the Chemistry section of your upcoming SSC exam. Frustrated, he slammed the book shut
Discovered by Ernest Rutherford; positively charged. Neutron: Discovered by James Chadwick; neutral charge. Electron: Discovered by J.J. Thomson; negatively charged. Atomic Number (Z): Number of protons in the nucleus. Mass Number (A): Sum of protons and neutrons.
Group 18 (Inert gases like Helium, Neon, Argon). Halogens: Group 17 (Fluorine, Chlorine, Bromine). Trends:
): Deuterium oxide. Used as a in nuclear reactors to slow down fast-moving neutrons. High-Yield Revision Tips for SSC Chemistry
Formed by the sharing of electrons between non-metals (e.g., CO2CO sub 2
