Choose the letter corresponding to the correct answer from the options A, B, C and D given below :
(i) The type of bonding in X will be :
A. ionic
B. electrovalent
C. covalent
D. molecular
(ii) X is likely to have a :
A. low melting point and high boiling point.
B. high melting point and low boiling point.
C. low melting point and low boiling point.
D. high melting point and high boiling point.
(iii) In the liquid state, X will :
A. become ionic,
B. be an electrolyte,
C. conduct electricity,
D. not conduct electricity.
Answer
(i) C → covalent
Reason : Since, X consists of molecules. Therefore, covalent bond is present.
(ii) C → Low melting point and low boiling point.
Reason : Covalent compounds have low melting and boiling points.
(iii) D → not conduct electricity.
Reason : Covalent compounds are non-conductor of electricity in solid, molten or aqueous state.
