Which property is typical of a covalent compound? A. They are extremely hard solids. B. They have low melting and boiling points. C. They conduct electricity. D. They have rigid crystal structures. E. They exist only as gases and liquids
Answers
Answer:
(B) Covalent Compounds usually have very low boiling and melting points which is because of the nature of covalent bonding which is inferior to what ionic bonding is.
Boiling point and melting point depends on the intramolecular as well as intermolecular forces of attraction which is much more due to ionic bonding than covalent bonding and hence (B) is justified to be the correct answer.
All the other options contain information which is contrary to what covalent compounds actually have !
Hope this helps you !
Answer:
B
Explanation:
A & D is wrong since O2 has covalent bond, which is gas. E is wrong since higher alkanes are solids and they are completely covalent( eg: diamond).
since the do not have free electron C is also wrong.
