1“Carbon prefers to share its valence electrons with other atoms of carbon or with atoms of other elements rather than gaining or losing the valence electrons in order to attain noble gas configuration.” Give reasons to justify this statement.Question 2

2026
Two statements are given, one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer from the options given below.24Assertion (A) : Carbon compounds can form chains, branched and ring structures. Reason (R) : Carbon exhibits the property of catenation.Tap an option to check your answer.
Question 7
2026
Two statements are given, one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer from the options given below.24Assertion (A) : Carbon shares its valence electrons with other atoms of carbon or with atoms of other elements. Reason (R) : The shared electrons belong to the outermost shells of both the atoms and lead to both atoms attaining the noble gas configuration.Tap an option to check your answer.
