Question

How many electrons does a carbon atom share with other carbon atom(s) in the formation of acetylene molecule?

• A. Three
• B. Two
• C. One
• D. Four

Answer 1

The correct option is A

Three

• Acetylene, also known as ethyne is an alkyne. Hence the molecule will have a triple bond in it.
• It is also the first member of the homologous series, hence it will contain only two carbon atoms.
• Therefore, the triple bond will exist between these two carbon atoms.
• In other words, each carbon atom shares three electrons with the other carbon atom
• And one electron with hydrogen atom.
• Its structure is given below.
