Regional planning deals with the efficient placement of land-use activities, infrastructure, and settlement growth across a larger area of land than an individual city or town.Regional planning is a sub-field of urban planning as it relates land use practices on a broader scale.n North America, regional planning may encompass more than one state, such as the Regional Plan Association, or a larger conurbation or network of settlements. North American regional planning is likely to cover a much larger area than the Regional Assemblies of the UK; both, however, are equally regional in nature.
Iodoform is the organoiodine compound with the formula CHI3. A pale yellow, crystalline, volatile substance, it has a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as the smell of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste.
Iodoform Test. A positive reaction with sodium hydroxide and iodine as reagents produce iodoform, which is a substance that is pale yellow in colour. Iodoform occurs as solid at ordinary room temperature because of three iodine atoms that are present in the molecule resulting in an increase in the molar mass.thanol tested for Iodoform test: To the iodine solution taken in a flask, add ethanol. Later add sodium hydroxide with continuous stirring. This reaction forms a crystalline yellow precipitate indicating a positive iodoform test.
