How many lone pairs of electrons are on the central carbon atom in a Lewis Structure of CHI3?

Chemistry
1 answer:
Alborosie3 years ago
5 0

There are zero lone pairs of electrons on the central carbon atom in a Lewis Structure of CHI3. The correct option is b.

Explanation:

Lone pair electrons are those valence electrons of an atom which do not take part in bonding or left after the bonds are formed.

CHI_{3}

carbon is the central atom in the compound having 4 valence electrons.

Each iodine molecule has 7 valence electrons.

H has 1 valence electron.

from the Lewis structure of CHI_{3}, it is seen that all four valence electrons of the carbon is involved in bonding with 3 atoms of iodine and 1 atom of hydrogen.

Thus when all valence electrons are involved in bonding no lone pair of electron is found in CHI_{3} that means zero lone pairs of electrons.

The octet of the iodine, carbon and hydrogen gets completed to form the compound.

How is the reaction rate affected by a temperature decrease?​
emmasim [6.3K]

Answer: When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. ... That greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other.
