Which molecular formula is also an empirical formula?

A. PCl3

B. C2H4

C. H2O2

D. C6H12O6

The molecular formula  is also an empirical formula.

Explanation:

Empirical formula of a compound represents the simplest positive integer ratio of constituting atoms.

Molecular formula may or may not be equal to empirical formula.

In general, if is the empirical formula then molecular formula is where n = 1, 2, 3......

                   Empirical formula                            Molecular formula

                                                                         or      

                           OH                                                 or

                                                                      or

Hence the molecular formula  is also an empirical formula.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the product of the pressure and volume is also constant
