Concept explainers

Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

Question

Which one of the following statements from Chapter 8 and 18 is FALSE?
O For a compound to be classified as aromatic, it must have an odd number of pairs
of n-electrons and must be fully conjugated, cyclic and planar.
O Inclusion of heteroatoms as part of the conjugated ring system renders the
molecule to be considered non-aromatic.
O Benzene is a six-membered ring where the n-electrons are equally shared across
all six carbons in the ring and thus it possesses 36 kcal/mol of resonance
stabilization energy.
O The key reaction in Chapter 18 is the EAS reaction, which stands for electrophilic
aromatic substitution.
O All EAS reactions follow the same three mechanistic steps: (1) generate the
electrophile, (2) capture the electrophile to give a carbocation intermediate, and
(3) loss of a proton to regain aromaticity.
