state number of covalent bond in H2O and ccl4 and give bond structure and Lewis structure in H2O and ccl4
Answers
Answer:
Water has two single covalent bonds.
There are four Covalent Bond present in ccl4
Explanation:
You can find a procedure for drawing Lewis structures at this location.
For H₂O, O must be the central atom
The skeleton structure is H-O-H.
O has 6 valence electrons, and each H has one.
You must arrange 8 electrons in pairs so that O has 8 and each H has two electrons in its valence shell.
You have eight valence electrons in your trial structure, so it has the correct number of electrons.
The trial structure has the correct number of electrons.
The formal charge on each atom is:
H = 1 - ½(2) = 0; O = 6 – 4 - ½(4) = 0
The Lewis structure of H₂O is

Carbon tetrachloride (CCl4) is a covalently bonded compound composed of a central carbon surrounded by 4 chlorine atoms in a tetrahedral structure. The Lewis diagram from carbon tetrachloride is:
