Assertion : Addition of HBr in the presence of peroxide on 1-methylcyclopentene gives four optical isomers as major product. Reason : The major product contains two different chiral carbon atom

When bromo benzene is monochlorinated, two Isomeric compounds A and B are obtained. Monobromination of A gives several isomeric products of molecular formula C_6 H_3 CI Br_2 , while monobromination of B yields only 2 isomers C and D . Compound C is identical with one of the compounds obtained from bromination of A , however D is totally different from any of the isomeric cómpounds obtained from the bromination of A , Give structures of A, B, C and D and also structures of four isomeric monobrominated products of A Support your answer with reasoning.

Monosaccharides containing an aldehyde group are called aldoses while those containing aketo group are called ketoses. The aldehyde group is always present at C_1 while the keto group is usually present at C_2 . All monosaccharides containing five and six carbon atoms have cyclic structures, furnaose (five membered) and pyranose (six membered). During ring formation, C_1 in aldoses and C_2 in ketoses becomes chiral and hence all these monosaccharides exist in two stereoisomeric forms called the alpha -anomer and the beta -anomer while C_1 and C_2 are called glycosidic or anomeric carbon atoms. In contrast, stereoisomers, which differ in configuration at any other chiral carbon other than the glycosidic carbon are called epimers. Two molecules of the same or different monosaccharides combine together through glycosidic linkage to form disaccharides. All monosaccharides (aldoses and ketoses) and most disaccharides reduce Tollens'reagent and Fehling's solution, undergo mutarotation and form osazones. Two forms of D-glucopyranose are called
