Which of the following has highest covalent character ?
BeF2
CaF2
BrF2
BaF2
As we learnt ,
Nature of compounds formed by alkaline earth metals -
Be and Mg generally form compounds with significant covalent character due to their small size and high polarising power. Other elements form ionic compounds. The ionc character increases down the group.
So , BeF2 has highest covalent character among the given options .
Therefore, option (1) is correct.
