💡 Solution & Explanation

Correct option: \(\text{A}\). The correct choice is \(\text{A}\), 3, 21. 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: 30. Number of 3° carbon and 1° hydrogen respectively in the following structure are : Me Me Me H H C C C C Me Me H Me Me (A) 3, 21 (B) 3, 23 (C) 2, 18 (D) 3, 18
