The polarity of alcohol molecules decreases as size of the molecule . The alcohol functional group contains the elements oxygen, hydrogen, and carbon. Balance this reaction.
Which functional group is found in alcohols quizlet?
The functional group of an alcohol is an –OH (hydroxyl) group bonded to a tetrahedral carbon atom (a carbon having single bonds to four other atoms).
Which of the following functional groups is present in alcohol molecules?
alcohol: Class of organic compounds containing a hydroxyl functional group.
What elements are present in an aldehyde quizlet?
A compound containing a carbonyl group bonded to a hydrogen; a -CHO group. In a condensed structural formula, the aldehyde group may be written showing the carbon-oxygen double bond as CH[double bond]O or, alternatively, it may be written -CHO.
What would the molecule C2H4 be classified as quizlet?
What would C2H4 be classified as? It would be classified as a alkene.
What are functional groups quizlet?
A functional group is a portion of a molecule that is a recognizable/classified group of bound atoms. … The functional group gives the molecule its properties, regardless of what molecule contains it; they are centers of chemical reactivity.
What are functional groups and why are they important quizlet?
A functional group is an atom or group of atoms that determines the chemical and, in part, physical properties of an organic compound. What are functional groups important in determining? The presence of a particular functional group in a molecules can be used to predict the type of reactions the molecule will undergo.
What is an alcohol functional group?
The functional group of an alcohol is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. The electronegativity of oxygen is substantially greater than that of carbon and hydrogen.
What is the element for alcohol?
Alcohols are organic molecules assembled from carbon (C), oxygen (O), and hydrogen (H) atoms.
How do you determine the functional group of alcohol?
Alcohols are subdivided by examining the carbon to which the hydroxyl group is bonded. If this carbon is bonded to one other carbon atom, it is a primary (1o) alcohol. If this carbon is bonded to two other carbons, it is a secondary (2o) alcohol. If it is bonded to three other carbons, it is a tertiary (3o) alcohol.
Which of the following is a primary alcohol quizlet?
Ethanol is a primary alcohol because the carbon connected to the hydroxyl group is connected to only one alkyl group.
Does alcohol contain a carbonyl group?
Alcohols contain the hydroxyl functional group and can be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to two alkyl groups. Aldehydes and ketones contain the carbonyl functional group.
What is the functional group in carboxylic acids?
The functional group in the carboxylic acids is the carboxyl group, -COOH. It is responsible for the typical reactions of carboxylic acids, which are weak acids . Vinegar is a dilute solution of ethanoic acid.
Which element do functional groups attach to?
Functional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties.
What are the functional groups common to all amino acids quizlet?
Every amino acid contains an amine group (-NH2), a carboxyl group (-COOH) and an R group called a side chain, bonded to a central carbon atom. The central carbon is the alpha carbon, it is named so because it is the carbon atom directly adjacent to a carboxyl functional group.
How can hydrocarbons be classified?
Hydrocarbons can be classified as either aromatic or aliphatic compounds, depending on the presence of a benzene ring. Aliphatic compounds can be divided into alkanes, alkenes, and alkynes, based on the presence of double or triple bonds in the chemical structure.
