Answer:
Explanation: Water and Benzene are insoluble in each other. The molecules in a drop of benzene are not diluted by water molecules from nearby water droplets due to steam distillation so each liquid would exert its own vapor pressure. two liquids exert pressure against external pressures independently
The correct answers are H2, NH3, KCI, O2
Answer:
The Fischer Projection formula of D-glucose is as shown in the attachment below.
The chiral centre that determines its name is the last carbon from the carbonyl group, C-6
Explanation:
Fisher projection formulas are used to show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar molecule are joined vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are joined horizontally using solid lines as well.
The horizontal bonds project out of the plane of the paper or screen towards the reader whereas vertical bonds project behind the plane of the paper or screen, away from the reader.
Glucose is an aldose sugar with two different optical isomers or enantiomers, D-glucose and L-glucose. The designation D- or L- depends on the configuration of the chiral or asymmetric carbon most distant from the carbonyl carbon of glucose. If the chiral carbon has the same configuration as D-glyceraldehyde, that the -OH roup on the right side of the carbon and -H group on the left, it is snamed D-glucose. However, if the chiral carbon has the same configuration as L-glyceraldyde, that is with the -OH group on the right and the -H group on the right, it is named L-glucose
