They also tend to have higher boiling point than most hydrocarbons due to the hydrogen bonding. A) B) O C) —O — D) O E) —O—H Answer: C Page Ref: 12.1 Learning Obj. An alcohol has a higher boiling point than an alkane with the same length carbon chain. Which of the following functional groups does not contain a carbonyl group? Definition. Which of the following is true of the alcohol functional groups in 2,3-butanediol? The alcohol functional group involves an oxygen atom that is bonded to one hydrogen atom and one carbon atom. (See chemical bonding for a discussion of hybrid orbitals.) Alcohols are organic compounds with hydroxyl group (-OH). ... Butanal contains which one of the following functional groups? Functional Groups. B) A group of organic compounds forms a family if they share the same characteristic atom or a group of atoms called the functional group. Alcohol is the ingredient found in beer, wine, and spirits that causes drunkenness. It is a class of organic compounds characterized by one or more hydroxyl (―OH) groups attached to a carbon atom of an alkyl group. Because of hydroxyl group, they are polar compounds and more water-soluble than simple hydrocarbons. It also reacts with 3-methyl-2-pentene to form 2,3-dibromopentane. In propanol, the functional group present is a alcohol ( − O H ) group as the suffix is alcohol. Ether: Ethers are a family of organic compounds in which the general structure contains an oxygen atom attached to two alkyl groups. Example: Methanol, also called methyl alcohol, (CH 3 OH) is the simplest alcohol. The carbon atom will be part of a larger organic structure. Which of the following families of organic compound is the least soluble in water? (For more information about alkyl groups, see Chapter 1 "Organic Chemistry Review / Hydrocarbons", Section 1.5 "IUPAC Nomenclature". An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Instead of trying to memorize both equations, we can build a general rule that bromine reacts with compounds that contain a C=C double bond to give the product expected from addition across the double bond. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. One way to indicate a generic alcohol would be with the formula \(\ce{R-OH}\). In chemistry, it is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. Esters have a pair of alkyl or aromatic groups attached to … The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides : Ester. Which of the following compounds will have the lowest boiling point? Alcohol - Alcohol - Structure and classification of alcohols: Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. The six-carbon sugar molecules glucose and fructose, for example, contain aldehyde and ketone groups, respectively, and both contain five alcohol groups (a compound with several alcohol groups is often referred to as a ‘polyol’). In propanone, the functional group present is a ketone (− ∣ C = O) group as the suffix is one. True or false? Alcohols. butanoic acid, heptanoic acid, hexanoic acid, or pentanoic acid? Bromine reacts with 2-butene to form 2,3-dibromobutane. C) A group of organic compounds forms a family if they differ by one CH group, called the functional group, in their structure. A single compound may contain several different functional groups. 13) Which of the following compounds contains an ether functional group? In propanoic acid, the functional group present is a carboxylic acid (COOH) group as the suffix is oic acid. Molecules with Multiple Functional Groups.
