Answer to Question #191415 in General Chemistry for amir

Question

Choose the compound(s) that can act as bases.

Answer 1

Basically the question that you have posted is not complete, you have forgotten to mention the option of the above question.

But from my side I want to tell you that, The compounds which do not have lone pairs on central metal atom do not work as bases.For example in $PCl_5$ the central atom that is $P$ have no lone pairs of electron so it will never behave as base.
