Explanation:
THE SIGMA BONDS ARE THE BONDS FORMED BY THE S-SUBSHELL OVERLAP WHERE AS THE PI BONDS ARE FORMED DUE TO P-SUBSHELL OVERLAP.
THE FIRST STEP TO DECIDE THE NUMBER OF LONE PAIR IN A COMPOUND IS CLEARLY THE STRUCTURE OF IT . IF YOU KNOW THE STRUCTURE OF A PARTICULAR COMPOUND THEN YOU CAN EASILY DECIDE WHAT IS THE NUMBER OF SIGMA BONDS AND LONE PAIR .
The first bond made be any atom is always the sigma bond . Even if the compound is having double bonds , the one of the two bonds is sigma .
Also , if you know the valency of a particular atom , you can decide the no of lone pairs in any compound of that water . For instance , say water . Oxygen has a valency of 6. It forms two bonds with hydrogen atoms , and hence is left with 4 electrons in the outermost shell . The rest two have already been bonded with hydrogen atom by formation of a single bond . So 4 electrons stands for 2 lone pairs and hence H2O has two lone pairs . Rest of the things , you'll learn automatically as you proceed further in the subject . All the best for your journey with science . All the best !!
