• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (B)

The correct options are
A

B

What do you mean by molecular formula ?
$\Rightarrow$ Molecular formula indicates the simple numbers of each type of atom in a molecule of a molecular substance.
Therefore,

$C{H}_{3}C{H}_2-O-N=O$ $\Rightarrow C_2{H}_{5}N{O}_2$
$C{H}_{3}CHO\Rightarrow C_2{H}_{4}O$
Therefore,
Option (a) and (b) have same molecular formula.
