Choose the correct option based on the statements given below:
Statement 1: Carbon always shares electrons and forms covalent bond with other elements.
Statement 2: C+4 and C−4 ions are highly unstable.
Choose the correct option based on the statements given below:
Statement 1: Carbon always shares electrons and forms covalent bond with other elements.
Statement 2: C+4 and C−4 ions are highly unstable.
The correct option is B Statement 1 and 2 are correct, and statement 2 is the correct reason for statement 1.
C−4 and C+4 are unstable.
C−4 is unstable because it would be difficult for the nucleus with six protons to hold on to ten electrons, that is, four extra electrons.
C+4 is unstable because it would require a large amount of energy to remove four electrons leaving behind a carbon cation with six protons in its nucleus holding on to just two electrons.
Carbon overcomes this problem by sharing its valence electrons with other atoms of carbon or with atoms of other elements. Not just carbon, but many other elements form molecules by sharing electrons in this manner.
