10 mL of NaOH were added to the funnel in order to extract the organic layer into a flask labeled Organic Layer.
Naphthalene benzoic acid chemical formula. EPA has classified naphthalene as a Group C possible human carcinogen. Benzoic acid with NaOH 7. The C stands for carbon and the H stands for hydrogen.
Write a balanced equation for the acid-base reaction that occurs when the carboxylic acid component of your mixture was extracted from the methylene chloride solution. Naphthalene the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms. The chemical molecular formula of naphthalene is pretty easy to remember.
In general the total change in enthalpy Δ H is given as the change in internal energy Δ U plus any pressure-volume work Δ PV that accompanies the process. Molecular Formula C 7 H 6 O 2. Average mass 122121 Da.
Benzoic acid has a pKa of 417 while 2-naphthol has a pKa of 95. C 7 H 6 O 2. Since benzoic acids pKa is lower.
C6H5COO- Na H2O. Therefore benzoic acid is said to be an aromatic carboxylic acid. Monoisotopic mass 122036781 Da.
C 10 H 8. Benzoic Acid - cas 65-85-0 synthesis structure density melting point boiling point. Molecular Weight gmol Liquid.
C 7 H 6 O 2. C6H5COOH NaOH -----. 14092013 The acidic portion of benzoic acid is the carboxyl group and it reacts with a base to form a salt.
As such naphthalene is. Chemical formula C 10 H 8. The conjugate acid of bicarbonate H 2 CO 3 has a pKa of 64.
67 Physical Properties The chemical formula for naphthalene is C10H8 and its molecular weight is 12819 gmol. It consists of a carboxyl group attached to a benzene ring. 1 Naphthalene occurs as a white solid or powderthat is insoluble in water.
A mixture that contains benzoic acid 4-chloroaniline and naphthalene. This compound exists as a crystalline colorless solid under normal conditions. 14204 241.
Naphthalene with NaOH E. 18 Naphthalene has a strong mothball odor with an odor threshold of 044 mgm 3. Naphthalene C10H8 CID 931 - structure chemical names physical and chemical properties classification patents literature biological activities safetyhazardstoxicity information supplier lists.
Thus the benzoic acid could be separated from the neutral compound by extraction with either aqueous sodium bicarbonate or. It is an important hydrocarbon raw material that gives rise to a host of substitution products used in the manufacture of dyestuffs and synthetic resins. For example it reacts with sodium hydroxide NaOH to produce sodium benzoate.
Experimental One gram of a 11 mixture of benzoic acid and naphthalene were dissolved in 175 mL of dichloromethane and poured into a separatory funnel. CID 243 Benzoic acid. The 4-chloroaniline is separated first by extraction with hydrochloric acidSince no phenolic compound is present in this mixture two extractions with base solution are not required.
