Question

Boron is unable to form [BF6]3- give reason

Answer 1

Explanation:

Hii friend,

Here is your answer...

Boron (atomic no. :-5) having the electronic configuration 1s² 2s² 2p¹

Boron can able to form BF3 alone and it won't form [BF6]³- .

This is because Boron doesn't have vacant d-orbital to accommodate further electrons and thus it can able to extend its bonding beyond [BF4]- .

Hope this helps you a little!!!
