In unsaturated compound have
An unsaturated compound contains at least one double or triple bond between carbon atoms. Therefore, compounds with carbon-carbon double bonds, carbon-carbon triple bonds, or both are considered unsaturated. Hence, the correct answer is 'Carbon - carbon double and triple bond'.
Which is an acyclic compound :
An acyclic compound is one that does not contain a ring structure. Methane (CHâ‚„) is a simple aliphatic compound with no cyclic structure, whereas Benzene, Pyrrole, and Cyclobutane are cyclic compounds.
The compound which has one isopropyl group is :
An isopropyl group is a branched group with the structure -CH(CH₃)₂. 2-Methyl pentane contains one isopropyl group attached to the second carbon atom.
How many secondary carbon atoms does methyl cyclopropane have ?
The total number of secondary H-atoms in the structure given below are : $(CH_3)_2CHCH_2C_2H_5$
Which of the following radicals are bivalent ? (a) Ethylidene (b) Vinylidene (c) Benzyl (d) Methylidyne
Bivalent radicals are those that have two valence electrons available for bonding. Ethylidene (CH3-CH) and Vinylidene (CH2=C) are examples of bivalent radicals. Benzyl and Methylidyne are not bivalent radicals.
The derived name of $ ( CH_3) _4C $ is -
The derived name of $(CH_3)_4C$ is Tetramethylmethane. This name reflects the structure of the compound, which consists of a central carbon atom bonded to four methyl groups.
IUPAC name of $ (CH_3)_2 CH-CH_2 -CH_2Br $ is
The IUPAC name of $(CH_3)_2CH-CH_2-CH_2Br$ is 1-Bromo-3-methylbutane. According to the IUPAC nomenclature rules, the longest carbon chain is identified first, and then the substituents are named accordingly.
Which one of the following IUPAC name is correct ?
The IUPAC name of the compound Br(Cl) CH.CF3 is :
The correct IUPAC name for the compound Br(Cl) CH.CF3 is 2-bromo-2-chloro-1,1,1-trifluoroethane. The numbering should ensure the lowest possible locants for the substituents. Hence, the correct option is 2-bromo-2-chloro-1,1,1-trifluoroethane.
