Question
Give Uses of aldehydes and ketones
✓

Answer

→ In chemical industry aldehydes and ketones are used as solvents, starting materials and reagents for the synthesis of other products.
→ Formaldehyde is well known as formalin (40%) solution used to preserve biological specimens and to prepare bakelite (a phenol-formaldehyde resin), urea-formaldehyde glues and other polymeric products.
→ Acetaldehyde is used primarily as a starting material in the manufacture of acetic acid, ethyl acetate, vinyl acetate, polymers and drugs.
→ Benzaldehyde is used in perfumery and in dye industries. Acetone and ethyl methyl ketone are common industrial solvents. Many aldehydes and ketones, e.g., butyraldehyde, vanillin, acetophenone, camphor, etc. are well known for their odours and flavours.

The well known mineral fluorite is chemically calcium fluoride. It is known that in one unit cell of this mineral there are $4 \mathrm{Ca}^{2+}$ ions and $8 \mathrm{F}^{-}$ions and that $\mathrm{Ca}^{2+}$ ions are arranged in a fcc lattice. The $\mathrm{F}^{-}$ions fill all the tetrahedral holes in the face centred cubic lattice of $\mathrm{Ca}^{2+}$ ions. The edge of the unit cell is $5.46 \times 10^{-8} \mathrm{~cm}$ in length. The density of the solid is $3.18 \mathrm{~g} \mathrm{~cm}^{-3}$. Use this information to calculate Avogadro's number $($Molar mass of $\mathrm{CaF}_2=78.08 \mathrm{~g} \mathrm{~mol}^{-1} ).$
