$(A)$ Number of lone pairs on oxygen is 2 .
$(B)$ $FOF$ angle is less than $104.5^{\circ}$.
$(C)$ Oxidation state of $O$ is $-2$.
$(D)$ Molecule is bent ' $V$ ' shaped.
$(E)$ Molecular geometry is linear.
Correct options are:
$1 \mathrm{~mol}$ of an ideal gas is kept in a cylinder, fitted with a piston, at the position $\mathrm{A}$, at $18^{\circ} \mathrm{C}$. If the piston is moved to position $B$, keeping the temperature unchanged, then ' $x$ ' $L$ atm work is done in this reversible process.
$\mathrm{x}=$ . . . . . . $\mathrm{L} \mathrm{atm.} \mathrm{(nearest} \mathrm{integer)}$
[Given : Absolute temperature $={ }^{\circ} \mathrm{C}+273.15$, $\left.\mathrm{R}=0.08206 \mathrm{~L} \mathrm{~atm} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\right]$
