Draw the line structure for the ester that can be formed from the reaction of the acid anhydride and the alcohol given below. :0: :0: HO CH3-CH2-C-o-C-CCH2-CH3 acid anhydride alcoholarrow_forwardIndicate whether each statement is true or false. (a) Pentanehas a higher molar mass than hexane. (b) The longer the linearalkyl chain for straight-chain hydrocarbons, the higherthe boiling point. (c) The local geometry around the alkynegroup is linear. (d) Propane has two structural isomers.arrow_forward
- Compounds with nearly identical molar masses often havevery different physical properties. Choose the compound withthe higher value for each of the following properties, and explainyour choice.(a) Solubility in water: chloroethane or methylethylamine(b) Melting point: diethyl ether or 1-butanol(c) Boiling point: trimethylamine or propylaminearrow_forwardWhen the conjugate acid of aniline, C6H5NH3+, reacts with the acetate ion, the following reaction takes place: C6H5NH3+(aq)+CH3COO(aq)C6H5NH2(aq)+CH3COOH(aq) If Kafor C6H5NH3+ is 1.35105 and Kafor CH3COOH is 1.86105 , what is K for the reaction?arrow_forwardDraw the molecular structure for (a) an aldehyde that is an isomerof acetone, (b) an ether that is an isomer of 1-propanol.arrow_forward

(a) 3-chlorobut-1-ene Name the functional group: (b) butanedioic acid Name the functional group: (c) propanamide Name the functional group: (d) 3-methylbutanal Name the functional group:arrow_forwardAn alcohol is oxidized to a carboxylic acid, and 0.2003 g of the acid is titrated with 45.25 mL of 0.03811 M NaOH.(a) What is the molar mass of the acid? (b) What are the molarmass and molecular formula of the alcohol?arrow_forward
- The IUPAC name for a carboxylic acid is based on thename of the hydrocarbon with the same number of carbonatoms. The ending -oic is appended, as in ethanoic acid,which is the IUPAC name for acetic acid. Draw the structureof the following acids: (a) methanoic acid, (b) pentanoicacid, (c) 2-chloro-3-methyldecanoic acid.arrow_forwardExplain the geometry,hybridization and bond angle of carbon atom of a carboxylic acid?arrow_forwardGive a definition and an example for each class of organic compounds.(1) aldehyde (2) aromatic hydrocarbon (3) carboxylic acid(4) ester (5) amine (6) amide(7) nitrilearrow_forward
