Identify the correct sequence with respect to the strength of hydrogen bonding among the following.

The steam volatile compounds among the following are $:$
$(A)$ $o$-nitrophenol
$(B)$ $o$-nitroaniline
$(C)$ $p$-aminophenol
$(D)$ $p$-hydroquinone
Choose the correct answer from the options given below $:$

In which of the following molecules does hydrogen bonding occur? Why?
$CH_3OH, CH_3COOH, CH_4, Cl, HF, C_6H_6, NH_3, NF_3$

The correct statement/s about Hydrogen bonding is/are:
$A$. Hydrogen bonding exists when $H$ is covalently bonded to a highly electronegative atom.
$B$. Intermolecular $H$ bonding is present in $o$-nitrophenol.
$C$. Intramolecular $H$ bonding is present in $HF$.
$D$. The magnitude of $H$ bonding depends on the physical state of the compound.
$E$. $H$-bonding has a powerful effect on the structure and properties of compounds.
