Question
Draw the electron dot structure of ethyne and also draw its structural formula.

Answer

Ethyne is a hydrocarbon with molecular formula $C_2H_2$. Here two carbon atoms are bonded together by a triple covalent bond and one hydrogen atom is bonded with each carbon atom through a single covalent bond. Hence the electron dot structure of ethyne molecule can be representes as:
Structural formula of ethyne is: H ─ C ≡ C ─ H.
