We‘ve got your back. Try BYJU‘S free classes today! 5-sec-Butyl-4-iso-propyldecane Right on! Give the BNAT exam to get a 100% scholarship for BYJUS courses Solution The correct option is D5-sec-Butyl-4-iso-propyldecaneNumbering as per IUPAC (adsbygoogle = window.adsbygoogle || []).push({}); The longest carbon chain is of 10 carbons along with one isopropyl group present at fourth carbon and one secondary butyl group present at fifth carbon. Although IUPAC names for sec-butyl and isopropyl groups are 1-methylpropyl and 1-methylethyl respectively, both these names are recommended for IUPAC nomenclature. Hence, IUPAC name for the given alkane is: 5-sec-Butyl-4-isopropyldecane or, 4-(1-Methylethyl)-5-(1-methylpropyl) decane. Hence, options (C) and (D) are correct.Which is the correct IUPAC name of this compound?Hence, the correct IUPAC name is 3-Ethyl-4,4-dimethylbutane.
What is the correct IUPAC name of the compound shown below?It is 3 - Bromo - 1 - chlorocyclohex - 1 -ene with respect to the position of double bond which is on priority in given structure.
What is IUPAC example?The IUPAC name is therefore: 2,5,5-trimethyl-2-hexene. In example (2) the longest chain incorporating both carbon atoms of the double bond has a length of five. There is a seven-carbon chain, but it contains only one of the double bond carbon atoms. Consequently, the root name of this compound will be pentene.
How do you determine IUPAC name?IUPAC nomenclature is based on naming a molecule's longest chain of carbons connected by single bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds or atoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to a specific set of priorities.
