Chapter 24: Problem 55

Write the condensed structural formula for each of the following compounds: (a) 2 -pentanol, (b) 1,2-propanediol, (c) ethyl acetate, (d) diphenyl ketone, (e) methyl ethyl ether.

Short Answer

Expert verified
The condensed structural formulas for the given compounds are: (a) 2-pentanol: CH3CH2CH(OH)CH2CH3 (b) 1,2-propanediol: CH2(OH)CH2(OH)CH3 (c) ethyl acetate: CH3COOCH2CH3 (d) diphenyl ketone: (C6H5)2CO (e) methyl ethyl ether: CH3OCH2CH3

Step by step solution

01

(a) 2-pentanol

First, let's analyze the name "2-pentanol": - "Pent" indicates that the compound has 5 carbon atoms. - "an" indicates that it's an alkane, meaning it has single bonds between the carbon atoms. - "ol" indicates the presence of an alcohol group (-OH) attached to the carbon atom. - "2" indicates the position (numbering starts from 1) of the carbon atom to which the -OH group is attached. Putting all the pieces together, the condensed structural formula for 2-pentanol is CH3CH2CH(OH)CH2CH3.
02

(b) 1,2-propanediol

Analyze the name "1,2-propanediol": - "Prop" represents 3 carbon atoms. - "an" indicates that it's an alkane. - "diol" indicates the presence of two alcohol groups (-OH). - "1,2" indicates the position of the carbon atoms to which the -OH groups are attached. The condensed structural formula for 1,2-propanediol is CH2(OH)CH2(OH)CH3.
03

(c) ethyl acetate

Analyze the name "ethyl acetate": - "Ethyl" represents an ethyl group (CH3CH2-). - "acetate" is the ester (R-COO-R') deriving from acetic acid (CH3COOH). The condensed structural formula for ethyl acetate is CH3COOCH2CH3.
04

(d) diphenyl ketone

Analyze the name "diphenyl ketone": - "Di" indicates the presence of two phenyl groups (C6H5-). - "ketone" represents a carbonyl group (C=O) attached to an alkyl or aryl group. The condensed structural formula for diphenyl ketone is (C6H5)2CO.
05

(e) methyl ethyl ether

Analyze the name "methyl ethyl ether": - "Methyl" represents a methyl group (CH3-). - "ethyl" represents an ethyl group (CH3CH2-). - "ether" indicates the presence of an oxygen atom between the two alkyl groups. The condensed structural formula for methyl ethyl ether is CH3OCH2CH3.

Name or write the condensed structural formula for the following compounds: (a) para-dibromobenzene (b) $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{C} \equiv \mathrm{CC}\left(\mathrm{CH}_{3}\right)_{3}$ (c) trans-2-butene (d) cycloheptene (e) methylcyclopentane

You have samples of four compounds: diethyl ether, butane, 1 -chlorobutane, and ethylene glycol. You measure the boiling points of the compounds as \(-0.5^{\circ} \mathrm{C}, 35^{\circ} \mathrm{C}\), \(77^{\circ} \mathrm{C}\), and \(195^{\circ} \mathrm{C}\), but then lose the labels for each sample. Make the following predictions: (a) Which compound boils at $-0.5^{\circ} \mathrm{C} ?(\mathbf{b})\( Which boils at \)35^{\circ} \mathrm{C} ?(\mathbf{c})$ Which boils at \(77^{\circ} \mathrm{C} ?(\mathbf{d})\) Which boils at $195^{\circ} \mathrm{C} ?$

An unknown substance is found to contain only carbon and hydrogen. It is a liquid that boils at \(49^{\circ} \mathrm{C}\) at \(101.3 \mathrm{kPa}\) pressure. Upon analysis it is found to contain \(85.7 \%\) carbon and \(14.3 \%\) hydrogen by mass. At \(100^{\circ} \mathrm{C}\) and \(97.99 \mathrm{kPa}\), the vapor of this unknown has a density of \(2.21 \mathrm{~g} / \mathrm{L}\). When it is dissolved in hexane solution and bromine water is added, no reaction occurs. What is the identity of the unknown compound?

Monosaccharides can be categorized in terms of the number of carbon atoms (pentoses have five carbons and hexoses have six carbons) and according to whether they contain an aldehyde (aldo- prefix, as in aldopentose) or ketone group (keto- prefix, as in ketopentose). Classify glucose and fructose in this way.

Indicate whether each statement is true or false. (a) Tryptophan is an aromatic amino acid. (b) Lysine is positively charged at pH 7. (c) Asparagine has two amide bonds. (d) Isoleucine and leucine are enantiomers. (e) Valine is probably more water-soluble than arginine.
