Question

write the molecular, electronic, and structural formula of ethyne

Answer 1

Molecular formula- C2H2

Electronic formula & structural formula:

Answer 2

Answer : The molecular, electronic and structural formula of ethyne are shown below.

Explanation :

The given molecule is, Ethyne

The molecular formula of ethyne is, $C_2H_2$. That means ethyne contains 2 number of carbon atoms and 2 number of hydrogen atoms and the    two carbon atoms are bonded with triple bonds.

The electronic formula is also known as Lewis-dot structure.

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

As we know that carbon has '4' valence electrons and hydrogen has '1' valance electrons.

The total number of valence electrons in ethyne, $C_2H_2$ = 2(4) + 2(1) = 10

According to electron-dot structure, there are 10 number of bonding electrons and 0 number of non-bonding electrons.

Structural formula : It shows the number of bonds present between the atoms.

Therefore, the molecular, electronic and structural formula of ethyne are shown below.
