Question 8

$$HO -\underset {\underset {CH_{3}}{|\,\,\,\,}}{CH} - CH_{3} - COOH$$

$$HO - \underset {\underset {\,\,\,\,\,\,\,\,CH_{2} - CH_{3}}{|\,\,\,\,}}{CH} - CH_{2} - COOH$$

$$HO - \underset {\underset {CH_{3}}{|\,\,\,\,\,}}{CH} - CH_{2} - CH_{2} - COOH$$

$$HO - \underset {\underset {\,\,\,\,\,\,\,CH_{2} -CH_{3}}{|\,\,\,\,\,\,}}{CH} - CH_{2} - CHO$$

Question 9
