Question

Write the structural formulae of the following compounds:
(i) Ethanoic acid
(ii) Methanal
(iii) 1-Chloropropane
(iv) Nitromethane

Hint:

{Structural formulae} represent the exact arrangement of atoms in a molecule. {Ethanoic acid} is a carboxylic acid, {methanal} is the simplest aldehyde, and {1-chloropropane} is a halogenated hydrocarbon.

Answer 1

The structural formulae of the given compounds are: 1. Ethanoic acid (Acetic acid) - CH{3COOH} \[ \text{H} - \text{C} - \text{C} = \text{O} \] \[ \mid \mid \] \[ \text{H} \text{O - H} \] 2. Methanal (Formaldehyde) - HCHO \[ \text{H} - \text{C} = \text{O} \] \[ \mid \] \[ \text{H} \] 3. 1-Chloropropane - C{3H7Cl} \[ \text{CH}_3 - \text{CH}_2 - \text{CH}_2 - \text{Cl} \] 4. Nitromethane - CH{3NO2} \[ \text{CH}_3 - \text{NO}_2 \]
