Problem 3 : Write the structural formulae for the following compounds:

(a) Butanone (b) Methanoic acid (c) Ethyl methanoate (d) 2, 2-Dimethylpropanal

Solution :

(a) Butanone: [ \text{CH}_3 - \text{CO} - \text{CH}_2 - \text{CH}_3 ]

(b) Methanoic acid: [ \text{HCOOH} ]

(c) Ethyl methanoate: [ \text{HCOOCH}_2\text{CH}_3 ]

(d) 2,2-Dimethylpropanal: [ \text{CH}_3 - \text{C}(\text{CH}_3)_2 - \text{CHO} ]
