Ten carbon atoms in the LCC makes the compound a derivative of decane (rule 1), and the OH on the third carbon atom makes it a 3-decanol (rule 2). A racemic mixture (#50":"50#, #"R:S"#) suggests attack on either face of a planar carbocation intermediate, which indicates an #S_N1# reaction. Its general formula is R 2 CHOH. If this so... You have seven closed containers each with equal masses of chlorine gas (Cl2). The carbon atoms are numbered from the end closest to the OH group. (R)-3-methyl-3-hexanol is a tertiary alcohol, which is bulky.Thus, at ordinary temperatures, it tends to undergo #S_N1# reactions because it can't easily be back-side attacked (too much steric hindrance).. 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: According to the International Union of Pure and Applied Chemistry (IUPAC), alcohols are named by changing the ending of the parent alkane name (Chapter 12 "Organic Chemistry: Alkanes and Halogenated Hydrocarbons", Section 12.5 "IUPAC Nomenclature") to -ol. Provide two reasons why meiosis leads to genetic variation in diploid organisms. A compound with an OH group on a carbon atom that is attached to two other carbon atoms.
