Answer 1

Answer:

CH3 and C2H6

Explanation:

Answer 2

Answer:

CH₃ and C₂H₆ have same empirical formula.

Explanation:

The empirical formula is the simplest formula obtained by dividing the molecular formula with a number.

It gives the proportion of each element present in the compound however the exact number of each element is shown by only molecular formula.

For CH₃ : the empirical formula will is CH₃

For C₂H₆: the empirical formula will is CH₃ obtained by dividing the molecular formula by two.
