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.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
