Auxochrome molecules are comprised of groups such as amino‚ alkoxy‚ phenolic‚ sulfonyl‚ and carboxyl. Some examples of dyes are Malachite Green-which includes an amine group and ammonium‚ Para red-which includes nitro‚ azo benzene‚ phenol‚ and Congo red which includes an amino group‚ azo benzene‚ and sulfonate.

Introduction The case is all about the evolution of the Wrestling industry‚ rise and eventual fall of WWF (E). This case generates issues about the evolution‚ growth‚ competition‚ financial stress and other aspects of the wrestling company‚ WWF (E).

Did you take any medication during that time? Patient: Yes‚ I took three tablets of nitro glycerol and tried to rest but it did not help. Doctor: It says on your file that you were admitted by ambulance. Your ECG results show a ST elevation in II‚ III‚ aVF‚ and CK-MB higher than normal.

PRACTICAL 1 Title: Nitration of Acetanilide Aim : To observe how an Aromatic electrophilic Substitution reaction takes place via the nitration of Acetanilide i.e. how hydrogen on a carbon chain is replaced with a nitro group. Reagents and Chemicals: • Acetanilide (5g) • Glacial acetic acid (5mL) • Concentrated sulphuric acid (10mL &1.5mL) • Concentrated Nitric acid (2.0mL) • Methanol (30-50mL) Modification to experimental procedure: The experimental procedure

naturally occurring fats and oils are the fatty acid esters of glycerol. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters‚ such as nitro-glycerine‚ are known for their explosive properties‚ while polyesters are important plastics‚ with monomers linked by ester moieties. ------------------------------------------------- Structure & Bonding Esters contain a carbonyl centre‚ which

Chemical bonds are what make up the world. In bonds‚ elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds‚ they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability‚ as in the case of noble gases‚ an atom strives to complete its outer shell. Either losing or gaining electrons may do this‚ which concludes in an ionic bond

Quan Chapter 15: Redox Titrations 1. (A) Which of the following is true of a redox titration? (i) Since the redox reaction is spontaneous‚ the equilibrium constant does not have to be large for an effective titration. (ii) The titration effectiveness is increased when the two half-reaction potentials are far apart. (iii) Without an indicator the equivalence point cannot be detected. (iv) For an effective redox titration‚ the reducing agent must always be in the buret. (v) The equivalence
