Question

write the con

Chapter 16 Carboxylic Acids and Esters Name: 1) Write the condense structural formulas of the following compounds: Date: 3 methylpentanoic acid p-ethylbenzoic acid 4 m-hydroxylhexanoic acid 2) Which of the following compounds has the higher boiling point: butane, butanol, butanoic acid, and methyl ethanoate? Briefly explain why. 3) From the compounds of previous question, which is more soluble in water? Briefly explain why 4) Give the name of the carboxylic acid and alcohol used to prepare the ester methyl benzoate 5) Write the reaction of acid hydrolysis between methyl ethanoate and water.

Answer 1

solution :- D Condensed structural formule af 3 methyl fentanoic and CH3 CH2 CH (CH3) CH2 Cook Gordiused structural formula of P-ethylbenzoic acel P- C2H5 GH5 cool Condensed structural formule af 4-hydrong hexanoic acid ch, cho cho H) cho CHLC 0H er mu Among butane (CH3 CH2 CH2 CH3), butanol (CH₃ CH 2 CH 2 CH 2 Oh, buta noic acid (CH3 CH₂CH2COOH) and methyl ethanoate (ch3-2-0-CH3) , butanoic acid (CH3 CH2 CH2 Coon) has highest boiling point because its moleates form stronger hydrogen bends (dimens)

: o...nto CH₂ - CH2 - CH2 - Con &-CH2-CH2-CH3 . Answer: butanoic acid 3 Betanoic acid in more soluble in water because af its stronger hydrogen bonding with water molecals as it has two sites from where it Gn form hydrogen bond win water moleuls o-rama CH3 – CH2-Cho - on-oorn 4) Methyl benzoate can be prepared by Toxd-ok + H-o-cha x-d-o-CH3 +420 - Benzoic auel Mcthyl alcohol 5) CH3 -Cro- cats theo - CH₂ cool + CHzon
