Explain the acidic nature of carboxylic acids. View Solution Lamarckism fails to explain : View Solution Assertion : Corpuscular theory fails to explain the velocities of light in air and water. Reason : According to corpuscular theory, light should travel faster in denser media than in rarer...
Terminal alkynes (R-C equiv C-H) are weakly acidic in nature because of sp-hybridised state of the triple bonded carbon atom. Due to substantial s-character (50 %), the triple bonded carbon is electronegative in nature and this enables the release of H^(
(TPTZ)2]2+complex in an acidic medium [65]. Such colour changes are measured spectrophotometrically at 593 nm. This method requires specific conditions, including an acidic medium (pH 3.6) to facilitate iron solubility. The low pH decreases the ionisation potential that drives electron transfer ...
