C6H5COONa + H2O C6H5COOH + NaHCO3 C6H5COONa + CO2 + H2O H C6H5NH2 + HCl → C6H5N+H3Cl- 3. On the basis of solubility behaviour‚ determine the best solvent to differentiate the following pairs of compounds. a. CH3COOH (acetic acid) and CH3(CH2)5COOH The best solvent to use to differentiate acetic acid from heptanoic acid would be sodium bicarbonate (NaHCO3) as the stronger the acid‚ the more soluble it is in sodium bicarbonate. b. CH3CH2OCH2CH3 and CH3CH2OH The best solvent to use

additives to rubber and plastics‚paints and construction materials. Many terpenes are hydrocarbons‚ but oxygen-containing compounds such as alcohols‚ aldehydes or ketones are also found. Their building block is the hydrocarbon isoprene‚ CH2=C(CH3)-CH=CH2‚ Terpene hydrocarbons therefore have molecular formulas (C5H8)n. The larger structures are made up of several isoprene units‚ usually by "head-to-tail" linked isoprene units. However‚ isoprene it self does not carry out the process of building

When an alkene is mixed with bromine water‚ the alkene will de-colourise the bromine water. Primary Alcohol Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an –OH group. For example: Ethanol - CH3 – CH2 – OH The class of the alcohol depends on

The bandleader‚ Wesley Schultz‚ started off as an artist‚ drawing whatever he felt‚ and eventually replaced his talent and became a song artist. Wesley and Jeremiah started off childhood friends and began collaborating. They played gigs around New York. They moved to Denver‚ Colorado‚ bringing their talents

CH3COCH3 + 2[H] ( CH3CH(OH)CH3 Other points to note about this reaction are: • It is an addition reaction (there is only one product) • The mechanism is called nucleophilic addition • The nucleophile is H- which is provided by NaBH4 [pic] b) Comparison with hydrogen gas NaBH4 will reduce C=O double bonds but it will not reduce C=C double bonds e.g. CH2=CH-CHO + 2[H] ( CH2=CH-CH2OH To reduce both C=O and C=C
