Answer: A. [tex]C_2H_2[/tex] and [tex]C_6H_6[/tex]
Explanation: Empirical formula is the formula which shows the elements of a compound in the simplest ratio of atoms and not the actual number of atoms as shown in molecular formula.
A) [tex]C_2H_2[/tex] and [tex]C_6H_6[/tex] : Empirical formula for [tex]C_2H_2[/tex] is [tex]CH[/tex] and [tex]C_6H_6[/tex] is [tex]CH[/tex]
B) [tex]C_2H_2[/tex] and [tex]C_2H_4[/tex]: Empirical formula for [tex]C_2H_2[/tex] is [tex]CH[/tex] and [tex]C_2H_4[/tex] is [tex]CH_2[/tex]
C) [tex]CH_2[/tex] and [tex]C_6H_6[/tex]: Empirical formula for [tex]CH_2[/tex] is [tex]CH_2[/tex] and [tex]C_6H_6[/tex] is [tex]CH[/tex]
D) [tex]CH[/tex] and [tex]C_2H_4[/tex]: Empirical formula for [tex]CH[/tex] is [tex]CH[/tex] and [tex]C_2H_4[/tex] is [tex]CH_2[/tex]
The pair of compounds that share the same empirical formula is[tex]\rm C_2H_2\;and\;C_2H_6[/tex].
Empirical formula can be used to describe the number of atoms in a molecule in the simplest ratio form.
The empirical formula gives the simple molecule information, that has been repeated a number of times:
- In [tex]\rm C_2H_2\;and\;C_2H_6[/tex]:
[tex]\rm C_2H_2[/tex] has the empirical formula = [tex]\rm (CH)_2[/tex] = CH
[tex]\rm C_6H_6[/tex] has the empirical formula = [tex]\rm (CH)_6[/tex] = CH
- In [tex]\rm C_2H_2\;and\;C_2H_4[/tex]:
[tex]\rm C_2H_2[/tex] has the empirical formula = [tex]\rm (CH)_2[/tex] = CH
[tex]\rm C_2H_4[/tex] has the empirical formula = [tex]\rm (CH_2)_2[/tex] = [tex]\rm CH_2[/tex]
- In [tex]\rm CH_2\;and\;C_2H_4[/tex]:
The empirical formula of [tex]\rm CH_2[/tex] = [tex]\rm CH_2[/tex]
[tex]\rm C_2H_4[/tex] has the empirical formula = [tex]\rm (CH_2)_2[/tex] = [tex]\rm CH_2[/tex]
- In [tex]\rm CH\;and\;C_2H_4[/tex]:
The empirical formula of CH = CH.
[tex]\rm C_2H_4[/tex] has the empirical formula = [tex]\rm (CH_2)_2[/tex] = [tex]\rm CH_2[/tex]
Thus, the pair of compounds that shares the same empirical formula is[tex]\rm C_2H_2\;and\;C_2H_6[/tex].
