alcohol, any of a class of organic compounds characterized by one or more hydroxyl (―OH) groups attached to a carbon atom of an alkyl group (hydrocarbon chain).
What type of hydrocarbon is alcohol?
Alcohols are derivatives of hydrocarbons in which an –OH group has replaced a hydrogen atom. Although all alcohols have one or more hydroxyl (–OH) functional groups, they do not behave like bases such as NaOH and KOH. NaOH and KOH are ionic compounds that contain OH– ions.
What are alcohols How are they classified?
Alcohols are classified as primary, secondary or tertiary alcohols. The classification is done in accordance to where the carbon atom of an alkyl group is attached to the hydroxyl group. Most of the alcohols are known to be colourless liquids or even are said to behave as solid at room temperatures.
Are alcohols aliphatic hydrocarbons?
Aliphatic alcohols can be classified according to the number of R groups attached to the carbon with the hydroxyl group. If one R group is attached to that carbon, the alcohol is a primary alcohol.

Is alcohol an alkane?
Alkanes are molecules made of carbon and hydrogen atoms. … Alcohols can be alkanes, in terms of base structure, except that a hydroxyl group is attached to one or more of the carbons in the chain.
Is alcohol ionic or molecular?
Alcohols are covalent molecules; the –OH group in an alcohol molecule is attached to a carbon atom by a covalent bond.
Are alcohols hydrocarbons explain your answer?
Alcohols are all derivatives of hydrocarbons in which one or more of the hydrogen atoms in the hydrocarbon have been replaced by a hydroxyl group. The hydroxyl group is also responsible for imparting certain chemical and/or physical properties to the compound.
What is alcohol made of chemically?
Chemical structure of alcohol
Alcohols are organic molecules assembled from carbon (C), oxygen (O), and hydrogen (H) atoms. When 2 carbons are present, the alcohol is called ethanol (also known as ethyl alcohol). Ethanol is the form of alcohol contained in beverages including beer, wine, and liquor.
Is alcohol a compound element or mixture?
The short answer is yes, alcohol is a compound. Actually, alcohol is a GROUP of compounds which has -OH attached to atom Carbon in their chemical formulas. Some examples of alcohol are methanol, propanol, and butanol. Each of them has its own definite ratio of composition.
What are the types of alcohol in chemistry?
Chemistry, as a field, acknowledges three main types of alcohol: isopropyl, methyl, and ethyl alcohol. Each of these types of alcohol has different properties. Thus, it is essential for scientists and humans in common to differentiate which type of alcohol is which, if only for safety reasons.
Is alcohol an inorganic compound?
An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom.
What functional group is an alcohol?
The functional group of the alcohols 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.
Is ethanol an alcohol?
ethanol, also called ethyl alcohol, grain alcohol, or alcohol, a member of a class of organic compounds that are given the general name alcohols; its molecular formula is C2H5OH.
Is alcohol a mixture?
Drinking alcohol (ethanol) is a not a mixture, but a pure substance that happens to be a liquid at room temperature and typical atmospheric pressure. It’s about 43% ethanol, the rest is mostly water (which makes it a mixture).
Which compound is an alcohol quizlet?
alcohols are organic compounds that contain an –OH group attached to a saturated carbon atom. The general formula for an alcohol is R–OH, where R is an alkyl group. the IUPAC names of simple alcohols end in -ol, and their carbon chains are numbered to give precedence to the location of the –OH group.
What are alcohols and alkanes?
Alcohols are another ‘family’ of organic compounds, with ethanol being the best known member of the group. … Structurally, they are like alkanes but one of the H’s is replaced with an –OH group. They have some similar properties to alkanes, e.g. they burn, giving carbon dioxide and water.
