Question

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.

• (D) and (E) only
• (A) and (C) only
• (B) and (E) only
• (B) and (D) only

Answer 1

The Correct Option is B

Statement (A): True.Non-metals, being more electronegative, tend to attract electrons more strongly compared to metals.
Statement (B): False. Non-metals generally have higher ionization enthalpy than metals due to their smaller atomic sizes and higher nuclear charges.
Statement (C): True. Compounds formed between highly reactive metals (like alkali metals) and highly reactive non-metals (like halogens) are ionic in nature due to significant electronegativity differences.
Statement (D): False. Non-metal oxides are generally acidic in nature, not basic
Statement (E): False. Metal oxides are generally basic in nature, though some transition metal oxides may be amphoteric or acidic.
Thus, the correct statements are:
\[\text{(A) and (C) only.}\]
