Formula A: CH3
Formula B: C2H6
Given the two formulas representing the same compound:
Which statement describes these formulas?
(1) Formulas A and B are both empirical.
(2) Formulas A nd B are both molecular.
(3) Formula A is empirical and Formula B is molecular.
(4) Formula A is molecular and Formula B is empirical.

Haophan
(3) because Hydrocarbon compound has 3 forms:
CnH2n
CnH2n-2
And CnN2n+2

Correct option is (3).

Empirical formula:-Simplest whole number ratio of various atoms present in a compound.

Molecular formula:-The formula that gives the total number of atoms of each element in each molecule of a substance.

So, [tex]C_2H_6[/tex](formula B) is the molecular formula, and [tex]CH_3[/tex] (Formula A)is the empirical formula.

Hence, the correct option is (3).
