Question

Which pair shares the same empirical formula?

A. C2H2 and C6H6
B. C2H2 and C2H4
C. CH2 and C6CH6
D. CH and C2H4

Answer 1

Answer: A.
`C_2H_2` and
`C_6H_6`

Step-by-step 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)
`C_2H_2` and
`C_6H_6` : Empirical formula for
`C_2H_2` is
`CH` and
`C_6H_6` is
`CH`

B)
`C_2H_2` and
`C_2H_4`: Empirical formula for
`C_2H_2` is
`CH` and
`C_2H_4` is
`CH_2`

C)
`CH_2` and
`C_6H_6`: Empirical formula for
`CH_2` is
`CH_2` and
`C_6H_6` is
`CH`

D)
`CH` and
`C_2H_4`: Empirical formula for
`CH` is
`CH` and
`C_2H_4` is
`CH_2`
