Question:

What do you understand by bond pairs and lone pairs of electrons? Illustrate by giving one example of each type.

Answer:

Bond pairs – the pair of electrons which are involved in the formation of bond between bonded atoms are known as bond pairs.

Lone pairs – the pair of electrons present on bonded atoms which do not take part in bond formation are known as lone pairs.

The bond pair of electron can either be shared or transferred between two bonded atoms.

For example:


SELECT ex_no,question,question_no,id,chapter FROM question_mgmt as q WHERE courseId='2' AND subId='9' AND ex_no!=0 AND status=1 and id!=1346 ORDER BY views desc, last_viewed_on desc limit 0,10
