Mesocompounds are the optically inactive compounds whose rotation of one half is cancelled by the other
Compounds which cannot be optically active and whose rotation of one half is cancelled by the other
— meso compounds
Compounds which are optically inactive due to the cancellation of the optical rotation of one half by the other half- Meso compound
Taste of glycerol: sweet taste
Glycerol is sweet tasting.
Glycerol has a mild sweet taste.
Taste of glycerol – sweet
F-centres are electrons trapped in anion vacancies. They impart colour to the crystals.
AKSHAY PR.
F-centres:is a type of defect in which an anionic vacancy in a crystal lattice is occupied by one or more unpaired electrons.
F centers – sites occupied by electrons due to anionic vacancies in crystal lattice
Auto reduction
Reaction between copper sulphate and copper oxide= auto reduction
