Assertion- Carbon forms covalent compounds whereas lead form ionic compoundsReason- Carbons can also lose electrons to form C4+ while lead cannot.(A) Both assertion and reason are correct and reason is the correct explanation of assertion(B) Both assertion and reason are correct but reason is not the correct explanation of assertion(C) Assertion is correct but the reason is incorrect (D) Both assertion and reason are incorrect

The correct answer is:

(C) Assertion is correct but the reason is incorrect.

Carbon forms covalent compounds because it readily shares electrons to form covalent bonds due to its unique electronic configuration. Carbon typically forms four covalent bonds to achieve a stable electron configuration. This is due to its ability to both gain and lose electrons, making it versatile in forming covalent bonds with other elements, especially nonmetals.

On the other hand, lead (Pb) is a metal, and metals generally form ionic compounds, not because they cannot lose electrons, but because they tend to lose electrons to form positively charged ions (cations) and then bond with negatively charged ions (anions) through electrostatic attraction to form ionic compounds. The reason given in the assertion regarding lead is not accurate. Lead can lose electrons and form Pb²⁺ ions, which can participate in the formation of ionic compounds.

So, while the assertion about carbon is correct, the reason provided is not a valid explanation for why lead forms ionic compounds.
