What type of compound results from the reaction of an acid chloride and a 2° amine?
Butoxors [25]

Amide is produced when a 2° amine and an acid chloride combine.

Acid chloride: What is it?

  • The chemical name for acid chloride is RCOCl, where "R" stands for a side chain. They are reactive derivatives of carboxylic acids. In organic chemistry, an acyl group and a chlorine atom form an organic molecule known as an acyl chloride (also known as acid chloride).
  • A functional group identified by the RCO molecular formula is called an acyl group. Since acyl chlorides are often hazardous, handling them requires extra care.
  • They have the potential to produce HCl and organic compounds when they interact with water on the surface of the eye, irritating the eye. Anhydrous acid salts are neutral because it lacks an H+ donor.

Calculate the energy required to ionize a hydrogen atom to an excited state where the electron is initially in the n = 5 energy
SVETLANKA909090 [29]

. The energy of shells in a hydrogen atom is calculated by the formula E = -Eo/n^2 where n is any integer, and Eo = 2.179X10^-18 J. So, the energy of a ground state electron in hydrogen is:

E = -2.179X10^-18 J / 1^2 = -2.179X10^-21 kJ

Consequently, to ionize this electron would require the input of 2.179X10^-21 kJ


2. The wavelength of a photon with this energy would be:

Energy = hc/wavelength

wavelength = hc/energy

wavelength = 6.626X10^-34 Js (2.998X10^8 m/s) / 2.179X10^-18 J = 9.116X10^-8 m

Converting to nanometers gives: 91.16 nm


3. Repeat the calculation in 1, but using n=5.


4. Repeat the calculation in 2 using the energy calculated in 3.
