Similarity of fluorine and oxygen may not be attributed to?

Q. Assertion: Both rhombic and monoclinic sulphur exist as $S_8$ but oxygen exists as $O_2.$

Reason: Oxygen form $p\pi -p\pi$ multiple bond due to small size and small bond length but $p\pi -p\pi$ bonding is not possible in sulphur due to its larger atomic size than oxygen.

Q. $I$. Hydrogen bonds are a specific type of dipole-dipole interaction.
$II$. When hydrogen atoms are bonded to highly electronegative elements such as nitrogen, oxygen or fluorine electrons are shared unevenly between the hydrogen and the other atom.

Q. Assertion :In the formation of water molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason: Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

Q.

In the carbon family, the elements other than carbon do not form pπ - pπ bonds because the atomic orbitals are:
