Basic Chemistry Questions and Answers
Acetic acid and Chloroacetic acid have carboxylic acid (R-COOH) as the principle functional group. The structural difference between the two is the replacement of the hydrogen in acetic acid (H-CH2-COOH) with the chloro group in chloroacetic acid (Cl-CH2-COOH).
In 1827, a Scottish Botanist Robert Brown was the first to observe under an ultramicroscope, a peculiar motion of the certain particles within the pollen grains when put in water, that is now called the Brownian motion.
Most probable kinetic energy is the energy possessed by the maximum number of reactant molecules at a temperature T, and it is shown as a peak on the Maxwell-Boltzmann energy distribution graph (fraction of molecules versus Kinetic energy).
In the presence of moisture, PCl3 undergoes hydrolysis to release fumes of HCl gas.
PCl3 + 3H2O → H3PO3 + 3HCl
A Dimer is an additive product of two similar species. For example, when two molecules of NO2 combine it would give one molecule of N2O4. The N2O4 formed would be called as a dimer of NO2. Dimerization could be due to the formation of new covalent bonds or due to intermolecular hydrogen bonding. Here, in case of N2O4, it is due to covalent bonding.
