Chemistry
Which of the following is not a non polar covalent molecule:
- Chlorine
- Methane
- Hydrogen chloride
- Carbon tetrachloride
Answer
Hydrogen chloride
Reason — The covalent bond is said to be polar when the shared pair of electrons are not at equal distance between the two atoms. This results in the development of fractional positive charge and negative charge on them and they ionise in water. For example: hydrogen chloride.
