    Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms, e.g., hydrogen. After the formation of four bonds, carbon attains the electronic configuration of (a) helium           (b) neon                              (c) argon                              (d) krypton

Answer:

                  (b) Electronic configuration of carbon (C) = 2, 4 when it forms four covalent bonds by sharing its four valence electrons with hydrogen, it forms molecule like this Now, electronic configuration of C in Atomic number of Ne is 10. Its electronic configuration is Therefore, after the formation of four bonds, carbon attains the electronic configuration of neon.
