Problem 8 : Write the structural formulae for the following compounds:

(a) 3-Chloro-2-methylpentane (b) Butanal (c) Ethyl methanoate (d) 2,3-Dimethylbutane

Solution :

(a) 3-Chloro-2-methylpentane: [ \text{CH}_3 - \text{CH}(\text{CH}_3) - \text{CH}_2 - \text{CH}_2 - \text{CH}_2 - \text{Cl} ]

(b) Butanal: [ \text{CH}_3 - \text{CH}_2 - \text{CH}_2 - \text{CHO} ]

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

(d) 2,3-Dimethylbutane: [ \text{CH}_3 - \text{CH}(\text{CH}_3) - \text{CH}(\text{CH}_3) - \text{CH}_2 - \text{CH}_3 ]
