💡 Solution & Explanation

Correct option: \(\text{C}\). The correct choice is \(\text{C}\), CH - CH - CN. For hybridisation in hydrocarbons, a triple-bonded carbon is \(sp\), a double-bonded carbon is \(sp^2\), and a saturated tetrahedral carbon is \(sp^3\). Applying this to the indicated bond gives the hybridisation pair in the correct option. Recovered question text: 28. In which of the following species a carbon has sp-hybridization : (A) CH COOH (B) CH COCH (C) CH - CH - CN (D) 3 3 3 3 2
