Question

What is the valency of Carbon in Acetylene if its valency is two in $\mathrm{CO}$ and four in ${\mathrm{CO}}_2$ and ${\mathrm{CH}}_4$?

Answer 1

Valency

• The valency of an atom refers to its ability to combine with other atoms.
• The valency of an element determines the number of bonds that an atom can make as part of a complex.
• The electrons in the atom's outermost orbit are referred to as valence electrons.

Acetylene

• Acetylene is also known by the names Ethyne, Narcylen, and Vinylene.
• It is widely employed as a chemical component and a fuel.
• It is handled as a solution in its pure state, which is unstable.
• It is an unsaturated molecule in which the two carbon atoms are joined by a double bond.

Valency of Carbon in Acetylene

• Carbon in acetylene has a valency of four.
• The ability of elements to combine is referred to as valency.
• Valency is the number of elements provided or absorbed by an atom of an element in order for it to have the electronic configuration of the nearest noble gas.
• An individual carbon atom's four valence electrons from its outermost shell are involved in covalent bonding, giving it a valency of four.
