Why pernicious anaemia causes? What is peptide bond? Name an optically inactive alpha -amino acid.
An optically active compound A (C_(10)H_(14)) gets oxidised to benzoic acid (C_6H_5COOH) by alkaline KMnO_4 . However, compound B, which is an optically inactive isomer of A does not get oxidised by alkaline KMnO_4 . Identify A and B .
Different value of specific rotation of optically active amino acids are obtained at different pH. Explain.
(1) Give structure and IUPAC name of an optically active alkane having lowest molecular mass. Is there another alkane of the same molecular mass that is also optically active? (2) Give example of a compound which exhibits both optical & geometrical isomerism.
Give examples of : (1) an optically inactive compound cantaining asymmertic carbon atom, (2) an optically active compound containing no asymmetric carbon.
CH_(3)CH_(2)CHClCH=CH_(2) is optically active. Explain why it become optically inactive when reduced with H_(2)//Pt .
Give examples : (i) An optically active compound containing no asymmetric carbon atom. (ii) An optically inactive compound containing asymmetric carbon atom.
This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I : Meso tartaric acid is optically inactive. Statement - II : Meso tartaric acid has plane of symmetry.
Racemic tartaric acid and meso - tartaric acid are both optically inactive - why?
