o-hydroxybenzaldehyde shows only weak Vanderwal's forces of attraction while in $p$ hydroxy benzaldehyde there is strong Vanderwal's forces of attraction in solid state

o-hydroxybenzaldehyde shows association of the molecules while in $p$-hydroxy benzaldehyde there is no association among the molecules

o-hydroxybenzaldehyde shows intramolecular hydrogen bonding while in $p$-hydroxy benzaldehyde there is no intramolecular hydrogen bonding

p-hydroxybenzaldehyde, shows intramolecular hydrogen bonding while in o-hydroxy benzaldehyde there is stronger intermolecular hydrogen bonding

Acetone reacts with $\mathrm{NH}_2-\mathrm{NH}_2 / \mathrm{KOH}$ in Glycol on heating to form the saturated hydrocarbon, Butane

Acetone undergoes reaction in presence of $\mathrm{Ba}(\mathrm{OH})_2$ on heating to form 4-Methylpent-3-en-2-one

Acetophenone on reaction with $\mathrm{I}_2 / \mathrm{Na}_2 \mathrm{CO}_3(\mathrm{aq})$ does not undergo any reaction due to the presence of deactivating $-\mathrm{COCH}_3$ group

Acetophenone cannot be prepared on reacting Benzoyl chloride with Dimethyl cadmium in ether solvent
