What are halogens?
The place on campus where you may find chemistry professors' offices
What is the 3rd floor of Turner Hall?
This term refers to the ability of a molecule to donate a proton (H⁺), a key feature in acids
What is proton donor or Bronsted-Lowry acid?
This type of organic compound contains a carbon chain bonded to a halogen atom
What is a haloalkane (or halogenated hydrocarbon)?
This organization was established in 1923 to promote the professional development of Black chemists and chemical engineers
What is the National Organization for the Professional Advancement of Black Chemists and Chemical Engineers (NOBCChE)?
States that atoms tend to bond in such a way that each atom has a full outer electron shell, typically consisting of eight electrons
What is the Octet Rule?
The number of programs the HU Department of Chemistry has
What is 4?
This principle asserts that the reaction of a system at equilibrium will shift to counteract any disturbance, according to the changes in pressure, temperature, or concentration
What is Le Chatelier’s Principle?
This is the IUPAC name for the simplest alkene
What is ethene (or ethylene)?
This element, discovered by Marie Curie and her husband Pierre Curie, is famous for its radioactivity and was the first element to be isolated from a radioactive mineral
What is radium?
Left to right across a period in the periodic table, this property of elements generally increases due to an increased nuclear charge
What is electronegativity?
The current chair of the chemistry department
Who is Dr. Kesete Ghebreyessus?
This class of organic compounds contains a carbonyl group (C=O) bonded to at least one alkyl group or hydrogen atom
What is a ketone?
This type of isomer, where two molecules are non-superimposable mirror images of each other, is known as this
What is a chirality or enantiomer?
This scientist discovered that cathode rays are composed of negatively charged particles, which led to the identification of the electron
Who is J.J. Thomson?
This rule states that electrons will fill orbitals starting with the lowest energy first, and no orbital can hold more than two electrons with opposite spins
What is the Aufbau Principle?
The Hampton University Chemistry department faculty member who retains a membership with NOBCChE
Who is Dr. Waddell?
Type of reaction occurs when an electrophile adds to a double bond or a triple bond, resulting in the breaking of the pi bond and the formation of two new σ bonds
What is electrophilic addition?
This is the IUPAC name for the molecule CH₃CH₂CH₂OH, a simple alcohol that is also commonly used as a solvent in organic reactions
What is propan-1-ol?
