Specify the configuration of the following compounds in D or L designation. (a) Strategy: The sterochemicla descriptor D refers to an arrangement about a centre of chirality that is identical to the three-dimensional arrangement in D-(+)- glyceraldehyde in which the OH group on the chiral centre is on the right in the Fischer projection. Similarly, the other enatiomer of glyceraldehyde, which has _OH group on the chiral centre to the left is given L configuration. For carbohydrates (polyhdroxy aldehydes or ketones) the focus should be on the last chiral carbon (from the top) while for amino acids the focus should be on the chiral carbon carrying the NH_(2) group.

R,S-configuration is a useful tool for determination of enantiomers, diasteromers and homomers. If configuration of all chiral centers are opposite then structures are enantiomers, if all chiral centers have same configuration then they are homomers and if some have same confguration and some have opposite configuration then they are diastereomers. Among above structures find out enantiomeric structures:

Which of hte following is not diastereomer?

The number of chiral centers in glucopyranose and fructofuranose are:

The total spin resulting from d^(9) configuration is

2-Pentanol can coverted to 2-ethoxy pentane by two paths. In path I , configuration at chiral C is retained but at path II , configuration is inverted. Explain. , Tosyl (Ts) is .
