How is it removed? 6. Write the IUPAC names of the following compounds and clarify to 1°, 2°, and 3° amines? a) CH3-CH2-NH2 b) CH3-CH2-N-CH3 c) CH3-CH2-CH2-NH2 d) CH3-CH2-CH(NH2)-CH3.
Understand the Problem
The questions are seeking explanations and definitions related to various topics in chemistry, including polar compounds, isotonic solutions, allotropy, the stability of nitrogen, mercury removal, and classification of amines.
Answer
1. Polling checks device status. 2. Isotonic means equal solute concentration. 3. Allotropy: White, red, black phosphorus. 4. N2's triple bond is stable. 5. Mercury tailing is removed by zinc. 6. IUPAC names: Ethylamine, Methylethylamine, Propylamine, 2-Aminobutane.
- Polling is a method of checking the status of an external device in computers. 2. Isotonic solutions have equal concentrations of solutes leading to no net movement of water. 3. Allotropy refers to elements existing in different forms. Phosphorus has several allotropic forms, including white, red, and black phosphorus. 4. Nitrogen molecules are stable due to the triple bond between the atoms, making N2 inert. 5. Tailing of mercury refers to the formation of thin films, often removed by zinc or cleaning agents. 6. a) Ethylamine, 1° amine b) Methylethylamine, 2° amine c) Propylamine, 1° amine d) 2-Aminobutane, 1° amine.

More Information
The stability of nitrogen due to its triple bond makes it less reactive than many other molecules. Allotropy is fascinating as it shows how elements can exist in multiple structural forms.
Tips
Remember to identify if an amine is primary, secondary, or tertiary based on the number of alkyl groups attached to the nitrogen.
