Vedclass · Answer

(A) To determine the number of substances with $H$-bonding,we check for the presence of hydrogen atoms bonded to highly electronegative atoms like $N$,$O$,or $F$ in the molecule: $1$. Ethanol $(C_2H_5OH)$: Contains an $-OH$ group,so it exhibits $H$-bonding. $2$. Acetic acid $(CH_3COOH)$: Contains an $-OH$ group,so it exhibits $H$-bonding. $3$. Ethylamine $(C_2H_5NH_2)$: Contains an $-NH_2$ group,so it exhibits $H$-bonding. $4$. Trimethylamine $((CH_3)_3N)$: Nitrogen is bonded only to carbon atoms,so no $H$-bonding. $5$. Salicylic acid $(C_6H_4(OH)COOH)$: Contains $-OH$ and $-COOH$ groups,so it exhibits $H$-bonding. $6$. Ethanal $(CH_3CHO)$: Contains a carbonyl group but no $H$ atom directly bonded to $O$,so no $H$-bonding. Thus,the substances with $H$-bonding are Ethanol,acetic acid,ethylamine,and salicylic acid. The total count is $4$.

Observe the following substances: Ethanol,acetic acid,ethylamine,trimethylamine,salicylic acid,ethanal. In the above list,the number of substances with $H$-bonding is:
