Question

Work the following organic problems. Give explanations for your answers: a) Classify as alkane, alkene, or alkyne: C9H18 H | b) Classify as carboxylic acid, ester, and/or alcohol: CH3 – C – COOH | OH c) Write the structural formula of the ester formed by reacting methyl alcohol with acetic acid

Answer 1

a) C₉H₁₈   it is Alkene

because alkene have genral formula C_nH_2n where n = number of carbon atom

substitute these value in above formula C₉H₂₍₉₎ = C₉H₁₈ thus given compound is alkene

alkane have general formula C_nH_2n+2 and

alkyne have general formula C_nH_2n-2

b) CH₃ - CH₂ - COOH is Acid

because acid have functional group - COOH

ester have functional group R - CO - OR and

alcohol have fuctional group R - OH

c) the reaction is

CH₃OH + CH₃- COOH   CH₃ - CO - OCH₃ + H₂O

structural formula of the ester formed by reacting methyl alcohol with acetic acid is CH₃ - CO - OCH₃
