Is cellulose ketohexose or aldohexose? how does cellulose give result in seliwanoff’s test (any color change)?

Cellulose is an aldohexose

Explanation:

Cellulose is an aldohexose  , because , it has an aldehyde group present at one of the end .

Seliwanoff’s test

It is the test to differentiate between a ketose and an aldose .

The test is as follows -

If the sample is heated and it it readily gets dehydrated , then the sample is a ketose .

And , the reaction of   Seliwanoff’s reagent and  ketose , give a red color , which is the positive sign for the test .

But ,

the reaction of   Seliwanoff’s reagent and  aldoses , give a very light pink color .

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
