Question

In group 14 elements, the element with highest melting point is X and element with lowest melting point is Y. X and Y respectively are

• A. Si, C
• B. Si, Pb
• C. C, Sn
• D. Sn, C

Hint:

In group 14, the melting points decrease as we move down the group due to the increasing size and weaker bonding in heavier elements like Sn.

Answer 1

The Correct Option is D

In group 14 elements: - Silicon (Si) has a relatively high melting point. - Tin (Sn) has the lowest melting point. Thus, the correct order is Sn (lowest melting point) and C (highest melting point).
