The open-chain structure of a ketotriose has to be drawn and the optical activity also has to be explained. Concept introduction: Monosaccharides are organic molecules that have a general formula of ( C H 2 O ) n , in which the open chain of hydrocarbons that carries alcohol functional groups on all but one carbon. The remaining carbon may carry an aldehyde group (in the case of an aldose) or a ketone group (in the case of ketoses). Ketotriose is a three carbon sugar in which a keto group is present. Optical activity of a molecule is the interaction between molecule and plane-polarized light. Molecule having asymmetric center shows optical activity except mesocompounds ( Mesocompounds have a plane of symmetry in there structure.). Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

The open-chain structure of a ketotriose has to be drawn and the optical activity also has to be explained.

Concept introduction:

Monosaccharides are organic molecules that have a general formula of (CH2O)n, in which the open chain of hydrocarbons that carries alcohol functional groups on all but one carbon. The remaining carbon may carry an aldehyde group (in the case of an aldose) or a ketone group (in the case of ketoses).

Ketotriose is a three carbon sugar in which a keto group is present.

Optical activity of a molecule is the interaction between molecule and plane-polarized light.

Molecule having asymmetric center shows optical activity except mesocompounds (Mesocompounds have a plane of symmetry in there structure.).

Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.
