Iso propyl alcohol structure

\( \newcommand\) • • • • • • • • • • • • • • • • • • • Learning Objectives • Identify the general structure for an alcohol. • Identify the structural feature that classifies alcohols as primary, secondary, or tertiary. • Name alcohols with both common names and IUPAC names An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature. Most people are familiar with ethyl alcohol (ethanol), the active ingredient in alcoholic beverages, but this compound is only one of a family of organic compounds known as alcohols. The family also includes such familiar substances as cholesterol and the carbohydrates. Methanol (CH 3OH) and ethanol (CH 3CH 2OH) are the first two members of the homologous series of alcohols. Nomenclature of Alcohols Alcohols with one to four carbon atoms are frequently called by common names, in which the name of the alkyl group is followed by the word alcohol: Structural formula of methyl alcohol, ethyl alcohol, propyl alcohol, and isopropyl alcohol with the methyl, ethyl propyl, and isopropyl groups highlighted in green. According to the International Union of Pure and Applied Chemistry (IUPAC), alcohols are named by changing the ending of the parent alkane name to - ol. Here are some basic IUPAC rules for naming alcohols: • The longest continuous chain (LC...

Structure and classification of alcohols Similar to water, an alcohol can be pictured as having an s p 3 hybridized tetrahedral s p 3 hybrid orbitals. ( See One way of classifying alcohols is based on which tertiary alcohol has the hydroxyl group on a tertiary (3°) carbon atom, which is bonded to three other carbons. Alcohols are referred to as allylic or benzylic if the hydroxyl group is bonded to an allylic carbon atom (adjacent to a C=C double bond) or a benzylic carbon atom (next to a As with other types of organic • Name the substituents, and give their numbers as for an alkane or The first example below has a longest chain of six carbon atoms, so the root name is hexanol. The ―OH group is on the third carbon atom, which is indicated by the name 3-hexanol. There is a methyl group on carbon 3 and a Common names The common name of an alcohol alcohol. If the alkyl group is complex, the common name becomes awkward and the IUPAC name should be used. Common names often incorporate obsolete terms in the naming of the alkyl group; for example, amyl is frequently used instead of pentyl for a five-carbon chain.

Isopropyl alcohol or IPA is a name that is recognized even by the common people. Thanks to the hand sanitizers and electronic cleaning solutions that made it popular. But isopropyl alcohol uses are much wider than it’s known. Let’s dive into it; but before that respecting the chemistry, let’s have a briefing on its basics. Isopropyl Alcohol (IPA) Structure: • Isopropyl alcohol (IPA) Formula – C3H8O • Isopropyl alcohol IUPAC name: Propan-2-ol. • CAS No. of Isopropyl alcohol: 67-63-0 Let’s begin with the big fat application of Isopropyl Alcohol – Cleaning: I wouldn’t be exaggerating if I say “Our world revolves around electronic gadgets”. Day in and day out we need them for our work and leisure; to keep them going, they need regular maintenance, Any impairment would bring down efficiency or even worse would stop workflow. Dust and dirt are the regular culprits that need to be cleaned at reasonable intervals. If left unattended it may give rise to heating issues, loss of data, and at times short circuits. So it’s best they are given due attention. Different ways of cleaning: The simplest way of clearing dust is to use a microfiber cloth but this may not be the ideal method for thorough cleaning as well as for delicate handling. Compressed air cleaning guns can be used to focus cleaning in specific areas, water can also be used to wipe away dust but is not advisable for electronic circuits, in such instances Isopropyl alcohol (IPA) is the best alternate. IPA is an excellent so...
