Question

Basic radical consists of:
A. Positive charge
B. Negative charge
C. No charge
D. None of the above

Answer 1

Hint: A compound called sodium hydroxide, also known as lye or caustic soda. We know it very well and know about its ionisation. Recall the ions which were formed in its ionisation of sodium hydroxide.

Complete step by step answer:
• The ions formed after the removal or detachment of hydroxide ion $(O {{H} ^ {-}}) $ from a base is known as basic radical.
• For example when $NaOH$ is ionised, it forms $N {{a} ^ {+}} $ and $O {{H} ^ {-}} $ ions. Here, $NaOH$ loses $O {{H} ^ {-}} $ ion to form $N {{a} ^ {+}} $ ion which is known as basic radical.
• Some basic radicals are $N{{a}^{+}},B{{a}^{+}}^{+},C{{u}^{++}},{{K}^{+}},F{{e}^{+++}},$ etc.
• Basic radicals have positive charge on them.
• On electrolysis of a compound it is found that basic radical got deposited on cathode.
• Radicals commonly display paramagnetism. Electron spin resonance is the conclusive and broadly utilized strategy for describing radicals. The idea of the molecule bearing the unpaired electron and its neighbouring atoms can frequently be concluded by the EPR range.
Therefore, basic radicals have positive charge on them and hence, option A. is the correct one.

Additional information:
Opposite to basic radicals there exist acidic radicals which are formed as a result of removal of ${{H} ^ {+}} $ ion. These are negatively charged. Examples for acidic radicals are $SO_{4}^{2-}$ $,$ $NO_{3}^{-}$ , etc.

Note: Generally, we think that basic radical means that negative ion but it is false. But it is the opposite of it, so keep it in mind.
