Question

out of NaCl and AgCl which
are lower melting
point and why?​

Answer 1

Answer:

Explanation:

As Ag+ is much less electronegative than Na+ and K+, AgCl is much less ionic than NaCl and KCl and has the lowest melting point. There is considerable ionic character to the bonding in AgCl.

Answer 2

AgCl has a lower melting point.

• The electronic configuration of sodium ions in NaCl is as follows-
• ${1s}^{2} {2s}^{2} {2p}^{6}$
• The electronic configuration of Ag ions in AgCl is as follows-
• $[Kr] {4d}^{10}$
• Na ion has a noble gas type electronic configuration and Ag ion has pseudo noble gas like electronic configuration hence NaCl is more ionic than AgCl and has a high melting point than AgCl.
• So, NaCl have a higher melting point than AgCl.
