Question
Which of the following is correct according to the covalent bond?
- They have high melting and boiling point.
- They are formed in between the metals and non-metals.
- Covalent compounds are mostly soluble in water.
- They are formed by the sharing of electrons.
Hint:
Covalent bonds are formed when atoms share electrons with each other to complete their octet and achieve stability.
The correct answer is: They are formed by the sharing of electrons.
- Covalent bonds are relatively weaker hence the compounds have lower melting and boiling point.
- Covalent bonds are formed generally between non-metals and other non metals, ionic bonds are generally formed between metals and non metals.
