Answer
Explanation:
Step1: Identify atoms in (a)
In $O = C = O$, there is 1 carbon and 2 oxygen atoms. Molecular formula is $CO_2$, and since it cannot be simplified further, empirical formula is also $CO_2$.
Step2: Identify atoms in (b)
In $H - C\equiv C - H$, there are 2 carbon and 2 hydrogen atoms. Molecular formula is $C_2H_2$. Simplifying by dividing sub - scripts by 2, empirical formula is $CH$.
Step3: Identify atoms in (c)
In the given structure, there are 2 carbon and 4 hydrogen atoms. Molecular formula is $C_2H_4$. Simplifying by dividing sub - scripts by 2, empirical formula is $CH_2$.
Step4: Identify atoms in (d)
In $O - S - O - H$ and another $O - H$, there is 1 sulfur, 4 oxygen and 2 hydrogen atoms. Molecular formula is $H_2SO_4$. Since it cannot be simplified further, empirical formula is also $H_2SO_4$.
Answer:
(a) Molecular formula: $CO_2$, Empirical formula: $CO_2$ (b) Molecular formula: $C_2H_2$, Empirical formula: $CH$ (c) Molecular formula: $C_2H_4$, Empirical formula: $CH_2$ (d) Molecular formula: $H_2SO_4$, Empirical formula: $H_2SO_4$
