Question bank:
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 (CH₄) 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 : $(CH_3)_2CHCH_2C_2H_5$
No explanation available.
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 ?
No explanation available.
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.
The structure of 4-methylpentene-2 is
No explanation available.
Reasoning
Statement I : The general IUPAC name of esters is alkyl alkanoate.
Statement II: The simplest ester is HCOOCH3
No explanation available.
Reasoning Statement I : The IUPAC name for the compound $C_6H_5COOCH_2CH_2COOH$ is 3-benzoyloxy propanoic acid. Statement II : $C_6H_5CH_2O$ is called benzoyloxy group.
No explanation available.
Reasoning STATEMENT -1: 4-Methylphenol and phenylmethanol are functional isomers. STATEMENT -2 :Isomeric alcohols and phenols have different chemical properties and therefore they are functional isomers
Statement I is true because 4-Methylphenol (an aromatic alcohol) and phenylmethanol (benzyl alcohol) are functional isomers, which means they have the same molecular formula but different functional groups. Statement II is false because isomers with different functional groups are called functional isomers, but this difference in chemical properties is not the reason they are functional isomers. They are functional isomers simply because they contain different functional groups.
Carbon free radicals are -
Carbon free radicals contain an unpaired electron, which makes them paramagnetic. Paramagnetic substances are attracted to magnetic fields due to the presence of unpaired electrons.
