  • Answer:

     In a tertiary amine there aren't any hydrogen atoms attached directly to the nitrogen. That means that hydrogen bonding between tertiary amine molecules is impossible. In case of primary amines, hydrogen bonds can form between the lone pair on the very electronegative nitrogen atom and the slightly positive hydrogen atom in another molecule. Therefore primary amines have higher boiling point than tertiary amines.

  • Question: what is zwitter ion?

    Posted in: Chemistry | Date: 25/10/2015


    A zwitter ion is a compound with no overall electrical charge, but which contains separate parts which are positively and negatively charged. At neutral pH values, the amino group (-NH3+) has a positive charge and the carboxyl group (COO-) has a negative charge.

  • Question: what is aerosol?

    Posted in: Chemistry | Date: 25/10/2015


    An aerosol can be defined as a system of solid or liquid particles suspended in air or other gaseous environment. Aerosols vary in size and composition, they can be naturally or manmade generated, and thus there are a wide range of them, from flame synthesized nanoparticles and nanomaterials (good aerosols), with fundamentally new properties and functions because of their small size (<100 nm) to airborne particulate matter resulted from the industrial production of nanomaterials, and viruses that have a negative effect in visibility and human health (bad aerosols).

  • Answer:

    Electric field lines radiate from positive charge to negative charge. So If we take the case of positive charge placed somewhere then the field lines will be radiating from its source to infinity. The potential because of positive charge at any given distance (r) is given by, V=kQ/r, therefore potential depends upon the distance from charge , so its same for all points equidistant from charge. If we join all such points of equal potential then we get a locus of points perpendicular to electric field lines.
