(a)

Step by step solution

01

Carboxylic acids or acid derivatives

Carboxylic acids are the COOH- containing compounds, and acid derivatives are the compounds formed when the OH group of a carboxylic acid is replaced by Cl (acid chloride) or - NH2(amide).There are three types of acid derivatives: acid halides, esters, and amides.

02

Synthesis of phenylacetic acid

(a) Isopropyl alcohol is synthesized when phenylacetic acid is treated with LiAlH4 and further with H3O+. Another method is by treating phenylacetic acid with B2H6 and then with H3O+.

  1. propanoic acid
  2. phthalic acid
  3. calciumformate
  4. succinic acid
  5. dibromoacetic acid
  6. acetylsalicylate (aspirin)

  9. potassium fluoroacetate

Most of the Fischer esterification mechanism is identical with the mechanism of acetal formation. The difference is in the final step, where a resonance-stabilized carbocation loses a proton to give the ester. Write mechanisms for the following reactions, with the comparable steps directly above and below each other. Explain why the final step of the esterification (proton loss) cannot occur in acetal formation, and show what happens instead.

Dimethylamine(CH3) 2 NHhas a molecular weight of 45 and a boiling point of 7.40C. Trimethylamine, (CH3) 3N, has a higher molecular weight (59) but a lower boiling point(3.50C) . Explain this apparent discrepancy.
