IV. Phenol
  1. I-C; II-C; III-B; IV-A

  4. I-A;II-A; III-C;IV-B

Solution

Acetamide is basic due to the presence of lone pair of electrons of $\mathrm{N} ;$ it is also acidic because its conjugate base shows resonance.


(more stable due to -ve charge on $O$ )
Benzonitrile $\left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{C}=\mathrm{N}ight.$ ) acts as an electrophile (Lewis acid) due to electron deficiency of $\mathrm{C}$ of $\mathrm{CN}$ as well as nucleophile (Lewis base) in nature due to presence of lone pair electrons on $\mathrm{N}$; hence it is neutral Triethylamine and phenol are basic and acidic in nature respectively. ,
