Vedclass · Answer

(A) The boiling point of a compound depends on intermolecular forces such as dipole-dipole interactions and hydrogen bonding. $1$. $CH_3COOH$ (acetic acid) exhibits strong intermolecular hydrogen bonding and exists as a dimer,resulting in the highest boiling point. $2$. $CH_3CH_2CH_2OH$ (propan$-1-$ol) also exhibits hydrogen bonding,but it is weaker than that in carboxylic acids,so it has a lower boiling point than $CH_3COOH$. $3$. $CH_3COCH_3$ (acetone) and $CH_3CH_2CHO$ (propanal) are polar molecules exhibiting dipole-dipole interactions. Acetone $(CH_3COCH_3)$ has a higher boiling point than propanal $(CH_3CH_2CHO)$ due to higher molecular polarity and stronger dipole-dipole interactions. $4$. Comparing all,the order is: $CH_3CH_2CHO < CH_3COCH_3 < CH_3CH_2CH_2OH < CH_3COOH$,which corresponds to $II < IV < III < I$.

Column-$I$ (Name)	Column-$II$ (Formula)	Column-$III$ (Example)
$(A)$ Ketone	$(i)$ $R-CO-OH$	$(p)$ $CH_3CHO$
$(B)$ Carboxylic acid	$(ii)$ $R-CO-H$	$(q)$ $CH_3COOH$
$(C)$ Amide	$(iii)$ $R-CO-R'$	$(r)$ $CH_3CONH_2$
$(D)$ Aldehyde	$(iv)$ $R-CO-NH_2$	$(s)$ $CH_3COC_2H_5$

Increasing order of boiling points in the following compounds is:
$I$. $CH_3COOH$
$II$. $CH_3CH_2CHO$
$III$. $CH_3CH_2CH_2OH$
$IV$. $CH_3COCH_3$
