Question

Which of the following could be an empirical formula?

• A. $C_4{H}_8$
• B. $C_2{H}_6$
• C. $CH$
• D. $C_3{H}_6$

Answer 1

Answer: (C)

$CH$

Empirical formula is the simplest ratio of molecules present in a compound. So, in an empirical formula ratio of molecules cannot have a common factor.

$C_4{H}_8,C_3{H}_6$ can be written as $C{H}_2$ in empirical form.

$C_2{H}_6$ can be written as $C{H}_3$.
