Which one of the following is correct?
- A Thallium is more electropositive than aluminium
- B Boron has high electrical conductivity
- C An aqueous solution of ortho boric acid is generally used as a mild antiseptic
- D Boron \(-11\left({ }^{11} \mathrm{~B}\right)\) isotope has high ability to absorb neutrons
Answer & Solution
Correct Answer
(C) An aqueous solution of ortho boric acid is generally used as a mild antiseptic
Step-by-step Solution
Detailed explanation
Thallium electronegativity \(=1.62\) (Pauling scale) Aluminium electronegativity \(=1.61\) Boron is a bad conductor of electricity at low temperatures. B-11 isotope is a stable and non-radioactive isotope. An aqueous solution of orthoboric acid is generally used as a mild…
