    Geiger-Muller Counter: Diagram and Working Principle<\/strong><\/h3>\n\n\n\n

    Neat and Labelled Diagram<\/strong><\/h4>\n\n\n\n

    I will generate a labelled diagram of the Geiger-Muller counter<\/strong> for clear understanding.<\/p>\n\n\n\n

    Working Principle of Geiger-Muller Counter<\/strong><\/h3>\n\n\n\n

    The Geiger-Muller (G-M) counter<\/strong> is an instrument used to detect and measure ionizing radiation. It operates on the principle of gas ionization.<\/p>\n\n\n\n

    Working Procedure:<\/strong><\/h4>\n\n\n\n
      \n
    1. Radiation Entry:<\/strong>\n
        \n
      • When radiation (alpha, beta, or gamma) enters through the mica window<\/strong>, it ionizes the gas inside the metal tube.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Ionization of Gas:<\/strong>\n
          \n
        • The gas-filled chamber<\/strong> contains an inert gas (argon or neon) at low pressure.<\/li>\n\n\n\n
        • The high voltage applied between the central anode wire<\/strong> and the outer cathode<\/strong> creates an electric field.<\/li>\n\n\n\n
        • As radiation interacts with the gas, it ionizes gas molecules<\/strong>, producing positive ions and free electrons<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Avalanche Effect:<\/strong>\n
            \n
          • The free electrons move rapidly towards the anode<\/strong> due to the strong electric field, colliding with more gas molecules.<\/li>\n\n\n\n
          • This leads to a chain reaction, known as a Townsend avalanche<\/strong>, multiplying the ionization process.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Pulse Formation:<\/strong>\n
              \n
            • The movement of electrons generates a voltage pulse<\/strong>.<\/li>\n\n\n\n
            • The pulse is amplified and registered as a count<\/strong> on a meter, indicating radiation detection.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • Discharge Quenching:<\/strong>\n
                \n
              • To prevent continuous discharge, a quenching gas<\/strong> (such as alcohol or halogen) absorbs excess energy.<\/li>\n\n\n\n
              • This ensures the detector is ready for the next ionization event.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

                The G-M counter is widely used for radiation safety, nuclear physics experiments, and environmental monitoring.<\/p>\n\n\n\n

                IUPAC Name of Neopentane<\/strong><\/h2>\n\n\n\n

                The correct answer is:<\/p>\n\n\n\n

                D. 2,2-Dimethylpropane<\/strong><\/p>\n\n\n\n

                Explanation:<\/strong><\/h3>\n\n\n\n

                Neopentane (common name) is a branched alkane<\/strong> with the molecular formula C\u2085H\u2081\u2082<\/strong>. The correct IUPAC (International Union of Pure and Applied Chemistry) name<\/strong> follows these rules:<\/p>\n\n\n\n

                  \n
                1. Identify the Longest Chain:<\/strong>\n
                    \n
                  • The longest continuous carbon chain<\/strong> contains three carbon atoms (propane)<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                  • Numbering the Chain:<\/strong>\n
                      \n
                    • Two methyl (-CH\u2083) groups<\/strong> are attached to the second carbon<\/strong> of the propane chain.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                    • Naming the Compound:<\/strong>\n
                        \n
                      • Since two methyl groups are on carbon 2<\/strong>, we use the prefix “2,2-“<\/strong>.<\/li>\n\n\n\n
                      • The root name “propane”<\/strong> comes from the three-carbon backbone.<\/li>\n\n\n\n
                      • Hence, the correct IUPAC name is 2,2-Dimethylpropane<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

                        This structure is highly symmetrical, making it one of the most compact alkanes<\/strong>. It has a tetrahedral<\/strong> geometry and is a gas at room temperature.<\/p>\n\n\n\n
