Question
Write a short note on free radical.
✓
Answer
Free radical:
i. A species with unpaired electron is called free radical.
OR
An uncharged species which is electrically neutral and which contains a single electron is called free radical.
ii. A free radical is highly reactive, unstable and therefore has a transitory existence (short-lived).
iii. Free radicals are formed as reaction intermediate which subsequently react with another radical/molecule to restore stable bonding pair.
iv. In a carbon free radical, the carbon atom having unpaired electron is sp hybridized and has planar trigonal geometry.
v. The alkyl free radicals are classified as primary, secondary or tertiary depending upon the number of carbon atoms attached to the C-atom carrying the unpaired electron.
vi. Stability of alkyl free radicals decreases in the order 3° > 2° > 1° > methyl free radical.

Naina is a school going kid. Every morning her mother makes her drink a glass of milk. When she asked her mother that why she has to drink a glass of milk daily, her mother told her that it is beneficial in maintaining healthy bones and teeth. Regular consumption of milk is recommended because it is a rich source of calcium.
$i.$ In which form is calcium important for bones and teeth?
$ii.$ Calcium belongs to which family in the modern periodic table?
$iii.$ Write its electronic configuration.
$iv.$ Calcium contain how many valence electrons?
$v.$ Give any two$-$biological importance of calcium.
