Cellulose - Biomolecules
Cellulose is found in all plants and thus is the most abundant of all carbohydrates. It is the substance required to form cell walls and another structural features of the plants. Wood is approximately 50% cellulose and the rest is lignin. Paper and Cotton are basically composed of cellulose.
Pure cellulose is acquired by consecutively reacting flax, cotton or paper, wool with dilute alkali, dilute HCL or HF. This reaction alters mineral matter, water and ether. Cellulose is left behind like a white amorphous powder.
The heat of combustion for ethane, C 2 H 6 , is 52.0 kJ/g. How much heat could be released if 1 mol of ethane undergoes full combustion? Answer:
Covalent Bond Purely electrostatic attractions between ions are nondirectional, but with increasing covalent character the directional properties of valence orbitals become more
Which monomers can undergo free radical, cationic as well as anionic polymerisation with equal ease? CH2=CH2
Aldehyde is a carbonyl compound in which one valency of carbonyl carbon is satisfied by hydrogen atom and other by a alkyl group.
what is primary standard and secondary standard?
This is an acid-catalyzed addition to the double bond much like hydration, except that an alcohol rather than water is the nucleophile that reacts with the carbocation intermediate
