Question

When determining the steric number of a central atom, which of the following count as ONE electron group?

Question 3 options:

	lone pair of electrons
	triple bond
	single bond
	Each of the options listed above count as ONE electron group

Answer 1

While determining the steric number of a central atom, lone pair of electrons is treated as one elctron group.

Becuase Lone pair of electron in a orbital and the orbotal occupy the space hence lone pair of elctrons is treated as group of electrons.

Aswer option : 1) Lone pair of elctrons.

In triple bond / single bond a lone pair of electron is shared between both central atom and other atom bonded to it.

And hence single/triple bond cannot be treated as group of electrons.
