Question

A,B, and C are atoms of elements with atomoc number Z, Z+1, and Z+2 respectivey. If B has octet configuration the bond formed between A and C predominantly...

a)Ionic bond
b)Covalent bond
c)Dative bond
d)Hydrogen bond


​

Answer 1

Answer:

[ B] Covalent Bond

Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.

Answer 2

Answer:

The bond formed between A and C is an ionic bond. Therefore the option (a) is correct.

Explanation:

• As given the elements B with Z+1 atomic number have complete octet. They belong to group 18 or noble gases.
• It means that element A with Z atomic number belong to group 17. They are halogens which are highly electronegative.
• Then element C with Z+2 atomic number  belongs to group IA. They are also known as alkali metals which are electropositive in nature.

     Therefore the bond between element A and element C is a bond between a very electronegative and electropositive element.  That type of bond will be an ionic bond.
