93126.	How will you distinguish between the following pairs of terms? a. Hexagonal close-packing and cubic close-packing b. Crystal lattice and unit cell c. Tetrahedral void octahedral void
Answer» a. Hexagonal close packing : The particles in every second row are seated in the depression (viods) between the particles of the first row. The particles in the row will be be vertically aligned with those in the first row, and so on. This type of arrangement is know as `AB AB`... type and is called hep. Cubic close packing : If we start with a lexagonal layer of spheres and the second layer of spheres is arranged by placing the sheres over the holes in the first layer, one half of these holes can be filled by these spheres. With this arrangement, the third layer does neither resemble first, fifth resembles second, and this sequence is repeated with the addition of more layers, then this type of arragement is known as `ABC ABC ABC` type The arrangement is known as cubic close-packed arrangement. b. Crystal lattice: A well-ordered and regular arrangement of atoms, molecular,or ions in the three-dimensional space is called crystal lattic. If the particles are replaced by points, the crystal structure would be an array of points which is called lattic. Unit cell : It is the smallest repeated unit in a crystal lattic, e.g., in sodium chloride and caseium chloride, the unit cell is a cube. c. Tetraderal viods : The viods are surrounded by four spheres which lie at the varitces of a regular tetrahedron are called tetrahedral viods. These are smaller than octahedral voids. There are eight tetrahedral voids around each sphere. There are two voids per atom of crystal. The radius ratio is 0.225 Octahedral viods : The void which of surrounded by six spheres which lie at the vertices of a regular tetrahedron is known as octahedral void. There are six octahedral viods around each sphere. There is one viod per atom in a crystal. The radius ratio is 0.414.

93144.	Covalent compounds like alcohol and carbohydrates dissolve in water. Give reason.
Answer» Organic compounds mainly contains carbon and hydrogen. Hydrocarbon chain is hydrophobic or oleophilic. Polar hydrocarbons dissolve in water due to formation of hydrogen bonds with water. As hydrocarbon part increases, solubility in water decreases due to increase in oleophilic part. Thus hydrocarbons are miscible in organic solvents. Water is a polar covalent compound. Alcohols are also polar covalent compounds. According to solubility rules, "like solutes dissolves in like solvents" This why water cannot dissolve oil, which is a nonpolar covalent compound. There are many covalent or non-polar compounds that will dissolve in water like sugar, carbon dioxide gas, and many alcohols, but they do not break into ions the way ionic compounds do when they dissolve. They are basically pulled apart into smaller pieces of the same molecule. Usually if an organic or covalent compound is small, it is more likely to dissolve. The covalent compounds that dissolve do so because they tend to have parts of their molecules that are somewhat polar (a negative side and a positive side) just like water.
