JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
The covalent radii of atoms A and B are \(r_A\) and \(r_B\), respectively. The covalent bond length and total length of AB molecule are respectively
- A \((r_A + r_B), 2(r_A + r_B)\)
- B \(\dfrac{1}{2}(r_A + r_B), (r_A + r_B)\)
- C \((r_A + r_B), (r_A + r_B)\)
- D \(2(r_A + r_B), \dfrac{1}{2}(r_A + r_B)\)
Answer & Solution
Correct Answer
(A) \((r_A + r_B), 2(r_A + r_B)\)
Step-by-step Solution
Detailed explanation
The covalent bond length of the AB molecule is the internuclear distance between atom A and atom B. Bond length = \(r_A + r_B\) The total length of the AB molecule is the distance between the outermost boundaries of the two atoms along the internuclear axis. Total length =…
