Question

The equatorial and axial $P-Cl$ bond length (in pm) respectively in $PC{l}_5$ are

• A. 202,240
• B. 240, 202
• C. 200,400
• D. 200,410

Answer 1

Answer: (A)

$PC{l}_5$ geometry is trigonal bipyramidal axial bond length is slightly greater than equatorial bond length in this case.

$P-Cl$ equitorial is $202\mathring{A}$

and $P-Cl$ axial is $240\mathring{A}$
