Explanation:

where is halides plz tell.....

Thank u

Answer 2

Answer: b) BF₃ does not exist as an ionic trihalide.

Explanation: Your question is incomplete so let me complete the question for you. This question consists of four options :

a)AlF₃

b)BF₃

c)GaF₃

d)InF₃

Boron being the center atom in BF₃ is small in size and thus has more covalent character. It has only three valence electrons in its valence shell and rather shares electron than donates it. BF₃ further reacts with lewis bases like NH₃ to form an adduct.

But in  the other option as in

• Al -[Ne]3s²3p¹:It has a larger size and thus can donate its three electrons to the three fluorine and still be in its complete octet.
• Ga-[Ar]3d¹⁰4s²4p¹-Here also as size increases ionic character increases and thus easily donates the three electrons and forms GaF₃.
• In-[Kr}4d¹⁰5s²5p¹-InF₃ is the most ionic trihalide among the 4 options given.

All three options form ionic trihalide except BF₃.
