Plz plz explain purely. don't write only answer.It's urgent. ​

Answer 1

Answer:

Explanation:

Isoelectronic means the no of electrons are same so find the no of electrons in the options.

Isostructural means their structure is same for that find the hybridisation.

Formula for hybridisation:

= No of atoms attached to central atom + 1/2{valency of central atom - 2× no of oxygen atoms}

For cation:

=No of atoms attached to central atom + 1/2{valency of central atom - 2× no of oxygen atoms - charge}

For anion:

=No of atoms attached to central atom + 1/2{valency of central atom - 2× no of oxygen atoms + charge}
