Question

Which of the following statements is incorrect about ionic compounds.

i) ionic compounds are aggregates of oppositely charged ions.

ii) ionic compounds are formed by transfer of electrons.

iii) ionic compounds are formed by sharing of electrons.

iv) ionic compounds are formed between elements having difference in electronegativity

​

Answer 1

Answer:

iii) Ionic compounds are formed by sharing of electrons.

(Is the incorrect sentence)

Ans: Ionic compounds are formed by transferring electrons.

(Is the correct sentence)

Explanation:

1. The ionic compounds are the compounds that are formed by the transfer of electrons between metals and non-metals.

2. The bond formed between them by transferring the electrons is known as the ionic bond.

3. Due to the presence of oppositely charged ions, ionic compounds are held strongly by the electrostatic force of attraction.

Answer 2

From the given question the correct answer is:

iii) ionic compounds are formed by sharing of electrons.

this is the incorrect statement about ionic compounds.

BECAUSE

• in ionic bonds there is a transfer of elections making one atom positive and other negative so they attract each other .
• The ionic compounds are the compounds that are formed by the transfer of electrons between metals and non-metals.
• This is the case of covalent bonds .in case of covalent bonds elections are shared just so to complete it's octet.
• The bond formed between them by transferring the electrons is known as the ionic bond.
•  Due to the presence of oppositely charged ions, ionic compounds are held strongly by the electrostatic force of attraction.
