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. in ionic bonds there is a transfer of elections making one atom positive and other negative so they attract each other .
Which of the following statement is correct about ionic compounds?
– As ionic bonds are formed by transfer of electrons, these bonds are much stronger, and thus have a high melting and boiling point. Hence, we can see that options B, C, and D are correct regarding ionic compounds. Note: Electricity is conducted through free electrons in a compound.
Which of the following statement is incorrect the formation of ionic compound depends upon?
The formation of ionic compounds depend upon the ease of formation of the positive and negative ions from the respective neutral atoms.

Which of the following is are ionic compounds?
Sodium chloride, sodium bromide,lithium chloride and lithium bromide are the ionic compound. Explanation: An ionic compound is composed of cation and anion and by the electrostatic force of attraction.
Which of the following is Favourable condition for formation of ionic bond?
The favourable condition for the formation of ionic bond is: Low ionization energy of metal so that it will easily lose electrons to form cation. High electron affinity of non-metal so as it could accept the electron and form an anion. Large size cation so that it has less polarizing power.
Which of the following is incorrect for chemical reaction?
∴ statement B is incorrect for a chemical change.
Which of this statement is incorrect all object of a class?
Which of this statement is incorrect? Explanation: All object of class share a single copy of methods defined in a class, Methods are allotted memory only once. All the objects of the class have access to methods of that class are allotted memory only for the variables not for the methods.
Which of the following statement is incorrect about patterns of demand generated by the customer?
The statement which is incorrect is- Understanding patterns of business activity is unimportant. Patterns of Business Activity (PBA) are workload profiles describing the demand for particular services.
Which of the following is not ionic compound?
HCl and CCl4 are covalent compounds; hence they cannot be ionic. Covalent bonding are found in non-ionic substances.
What makes compounds ionic?
Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge.
What are ionic compounds formed from?
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
Which of the following statement is correct about a chemical reaction?
The correct answer is Chemical reaction involves breaking and making of chemical bonds. Chemical reaction means breaking and making of chemical bonds to convert product from reactant.
Which of the following statements is incorrect for a chemical reaction a heat may be given out but never absorbed B sound may be produced?
Answer is (a) Heat may be given out but never absorbed. Explanation: During chemical reaction heat may be absorbed or given out hence option a) is a wrong statement.
