JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
Identify the correct statements about p-block elements and their compounds. \((A)\) Non metals have higher electronegativity than metals. \((B)\) Non metals have lower ionisation enthalpy than metals. \((C)\) Compounds formed between highly reactive nonmetals and highly reactive metals are generally ionic. \((D)\) The non-metal oxides are generally basic in nature. \((E)\) The metal oxides are generally acidic or neutral in nature.
- A \((D)\) and \((E)\) only
- B \((A)\) and \((C)\) only
- C \((B)\) and \((E)\) only
- D \((B)\) and \((D)\) only
Answer & Solution
Correct Answer
(B) \((A)\) and \((C)\) only
Step-by-step Solution
Detailed explanation
As electronegativity increases non-metallic nature increases. Along the period ionisation energy increases. High electronegativity difference results in ionic bond formation. Oxides of metals are generally basic and that of non-metals are acidic in nature.
