Question

A compound's molecular formula must always be different than the compound's empirical formula. TRUE FALSE

Answer 1

Answer: False

Step-by-step explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Example:
`CH_4` has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.

`C_2H_2` has molecular formula of
`C_2H_2` but
`CH` as the empirical formula.
