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.
can I get an explanation on how to do these? thankyou
C-Cl
- Structure of ethanol: C-OH
b) The boiling point of butanone is 80°C and the boiling point of 2-butanol is 100°C.
- Structure of butanone: C-(C=O)CH₃
- Structure of 2-butanol: C-CHOHCH₃
c) Ethanol is water soluble and octanol is not.
- Structure of ethanol (water soluble): C-OH
- Structure of octanol (not water soluble): ₂CCCCCCCOH
d) Hexanal is not water soluble but glucose is.
- Structure of hexanal: C-(CH₂)₄-CHO
- Structure of glucose: ₂C-(CHOH)₄-CHO
These observations can be explained by considering intermolecular forces, molecular size, and the presence of functional groups that affect solubility and boiling points.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3d00dd04-d8ee-4cd6-8a8c-b87b8cff4d7f%2F628e1905-6ed3-4bd4-b798-1768b0ebc0ea%2Fhezlws9_processed.jpeg&w=3840&q=75)
