b) (i) Step 1: Count the number of carbon atoms. There are 4 carbon atoms in the structure. Step 2: Count the number of hydrogen atoms. The -COOH group has 1 H. The left carbon of the C=C bond has 1 H. The right carbon of the C=C bond has 1 H. The -CH_2OH group has 2 H on the carbon and 1 H on the oxygen. Total H = 1 + 1 + 1 + 2 + 1 = 6 hydrogen atoms. Step 3: Count the number of oxygen atoms. The -COOH group has 2 O atoms. The -CH_2OH group has 1 O atom. Total O = 2 + 1 = 3 oxygen atoms. The molecular formula is C_4H_6O_3. (ii) • -C=C-: Alkenes • -OH: Alcohols • -COOH: Carboxylic acids (iii) • aqueous bromine: The reddish-brown color of aqueous bromine decolorizes due to the presence of the C=C double bond. • aqueous sodium carbonate: Effervescence (fizzing) is observed as carbon dioxide gas is produced due to the reaction of the carboxylic acid group with the carbonate. (iv) The addition polymer forms by breaking the C=C double bond.
