A regional planner is often called a city planner or urban planner if his or her work mainly involves urban planning and urban design. City and town planning can involve facilities and infrastructure such as hospitals, public housing, and recreational facilities.Regional planning can also involve non-urban areas. regional planner is often called a city planner or urban planner if his or her work mainly involves urban planning and urban design.

-The iodoform test or reaction is a chemical reaction where iodoform (CHI3) is produced by the multiple halogenation of a methyl ketone (a molecule containing the R-CO-CH3 group) in the presence of a base. R may be H, alkyl or aryl.The reaction can be used to produce CHCl3, CHBr3 or CHI3.thanal is the only aldehyde to give the iodoform reaction. Finally, OH- (aqueous) is added, which reacts with, for example, the triiodoacetone. CH3COCI3 + OH- â CHI3 + CH3COO-Iodoform, or triiodomethane (I3CH) is a pale yellow substance. It is therefore a solid at room temperature.
This page looks at how the triiodomethane (iodoform) reaction can be used to identify the presence of a CH 3 CH(OH) group in alcohols. Note: This reaction can also be used in testing for the CH 3 CO group in aldehydes and ketones.ummary of the reactions during the triiodomethane (iodoform) reaction We will take the reagents as being iodine and sodium hydroxide solution. This is being given as a flow scheme rather than full equations.
