is highly charged in nature and it can polarise the electron clouds of Cl to a large extent. So, electrons get shared between the two ions. Hence the compound is a covalent one, but the bond is polar covalent.
All other are ionic compounds.
Answer:
The correct option of the given question is 4) Bf3 i,e Boron Triflouride.
Explanation:
BF3 is covalent compound and the elements have covalent bond between them.
Since boron and Flourine mutually share their electrons.
The Bond is formed due to high ionisation energy of boron.
CaC3 is an ionic compound.
NAH is also an ionic compound.
similarly Baf2 has also ionic Bond, in the compound.
BF3 is a molecule consisting of an sp2 hybridization of Boron covalently bonded with 3 atoms of fluorine. The covalent bond tells us that electrons are shared, rather than lost by boron and gained by fluorine. This bond is formed because of Boron’s high ionisation energy
