Butanol has the chemical formula C4H9OH. d) In the molecule of butanol, there are C-C bonds, C-H bonds, a C-O bond and a O-H bond. Order these bonds from most to least polar e) On average, would you expect C-C to have longer or shorter bonds than C-H Briefly explain your answer. f) From the reaction 2.57 L of carbon dioxide was produced and captured. Calculate the number of molecules of carbon dioxide if the temperature was 25.0 C and the pressure 1. 01 × 105 Pa. g) The empirical and molecular formula for butanol is the same. Briefly explain why.
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.
