BASIC ORGANIC CHEMISTRY(QUIZ-5) 1 / 5 The isomers that can be interconverted through rotation around a single bond are: Conformers Diastereoisomers Enantiomers Positional isomers The isomers obtained due to (C - C)Â single bond rotation are called conformers. 2 / 5 Which of the following will have the least hindered rotation about carbon-carbon bond? Ethane Ethylene Acetylene Hexachloroethane Ethane (CH3 - CH3) has the least hindered rotation about (C- C)Â bond. 3 / 5 Lassigne's test is used for the detection of: N, S, and halogens C, H, and P C, H, and O C, S, and P The Correct Answer Is N, S, and halogens. 4 / 5 In Liebig's method for the estimation of C and H, if the compound also contains N, which of the following is kept near the exit of the combustion tube? Silver wire PbCrO4 Both (a) and (b) Cu gauge On heating the compound gas is evolved which is absorbed by Cu gauge. 5 / 5 An enantiomerically pure acid is treated with racemic mixture of an alcohol having one chiral carbon. The ester formed will be Optically active mixture Pure enantiomer Meso compound Racemic mixture When optically active acid reacts with racemic mixture of an alcohol, it forms two types of isomeric esters. In each, the configuration of the chiral centre of acid will remain the same.So, the mixture will be optically active. Your score isThe average score is 80% 0% Restart quiz
