Question

Select the incorrect statement-
A. Ionic compounds are generally brittle
B. Ions are the fundamental units of ionic compounds
C. Formation of ionic bonds involve sharing of electrons
D. NaCl is an ionic compound

Answer 1

Answer:

option c

Explanation:

ionic compounds involves lose or gain of electrons

Answer 2

The incorrect statement is C. Formation of ionic bonds involve sharing of electrons

• Ionic compounds are considered brittle in nature because they are held together by opposite charges to form a crystal lattice. A strong movement to this lattice by a physical force leads to breaking up the whole structure. Hence, option A is correct.
• The constituent particle to form an ionic compounds involves cations and anions. Hence, option B. Ions are the fundamental units of ionic compounds is correct.
• Ionic compounds cannot be formed by sharing as their formation involves gain or loss of electron. Hence, option C is incorrect.
• NaCl is formed by cationic Na+ and anionic Cl- ions. Hence, constituents are ions therefore it's an ionic compound. So, option D is also correct.
