Frank Solutions Class 10 ICSE Chemistry Chapter 16: Alkynes

Alkynes are unsaturated hydrocarbons containing carbon-carbon triple bonds with acetylene (ethyne) being the most important member. The chapter details laboratory preparation of acetylene from calcium carbide and water, producing a gas that burns with a luminous, sooty flame due to high carbon content. Students learn that alkynes undergo addition reactions in two stages-first forming alkenes, then alkanes-when reacting with hydrogen or halogens. The acidic nature of terminal alkynes, where hydrogen attached to triply-bonded carbon can be replaced by metals like sodium, distinguishes them from alkenes. Industrial applications include oxyacetylene welding where acetylene combustion reaches temperatures above 3000°C, making it valuable for cutting and welding metals.

Frank Solutions Class 10 ICSE Chemistry Chapter 18: Carboxylic Acids

Carboxylic acids contain the carboxyl functional group (-COOH) combining carbonyl and hydroxyl groups, with acetic acid being the most studied example. The chapter explains their acidic nature arising from the release of hydrogen ions, though they are weaker acids than mineral acids because they partially ionize in water. Students learn that carboxylic acids react with alcohols in the presence of concentrated sulfuric acid to form esters through esterification-acetic acid and ethanol produce ethyl acetate with a fruity smell. The reaction with carbonates and bicarbonates producing carbon dioxide provides a simple test for acid identification. Understanding formic acid's unique property of containing both aldehyde and acid functional groups explains its stronger reducing ability compared to other carboxylic acids.
