Question

question which of the following is the molecular formula for the simplest alkyne, ethyne? select the correct answer below: o ch₄ o c₂h₄ o c₂h₂ o ch

Explanation:

Step1: Recall alkyne formula

Alkynes have the general formula $\mathrm{C_nH_{2n - 2}}$.

Step2: For simplest alkyne

The simplest alkyne has $n = 2$. Substituting $n = 2$ into $\mathrm{C_nH_{2n - 2}}$ gives $\mathrm{C_2H_{2\times2 - 2}}=\mathrm{C_2H_2}$.

Answer:

C. $\mathrm{C_2H_2}$
