Question

State True or False.

Bond energy of all the P-Cl bonds in $PC{l}_3$ and $PC{l}_5$ is same.

• A. True
• B. False

Answer 1

The correct option is B False

Bond energy of all the P-Cl bonds in $PC{l}_3$ and $PC{l}_5$ is different.

P-Cl bond energy in $PC{l}_3$ is higher than P-Cl bond energy in $PC{l}_5$ molecule.

P-Cl bond energy in $PC{l}_3$ is 325 kJ/mole, P-Cl bond energy in $PC{l}_5$ is 268 kJ/mole.

So statement is false and answer is B.
