Which stable molecule would probably not exist?
a. ch3oh
b. vh2o
c. ch3o
d. c2h2
e. c3h4

Option C= CH₃O

Explanation:

CH₃O would not exist as a stable molecules because,

The in this compound oxygen is not stable.

In order to stable the oxygen carbon should form the double bond with oxygen. While the valency of carbon is four. It already form three bonds with three hydrogen atoms in this compound.

There is one electron left to form the bond with oxygen. So, there are not enough electrons which could bonded with oxygen and form stable compound.

Option (d) is the correct answer.

Explanation:

An ion is a specie that contains either a positive or a negative charge.

For example, , , , , etc are all ions.

Therefore, an ionic equation is defined as an equation that contains participating dissolved species in the form of ions.

For example,

Here, only AgCl is the precipitate as it is insoluble but rest of the species are ions as they have dissolved.

Thus, we can conclude that a complete ionic equation an equation showing all dissolved compounds as ions.
