Here's the answer...

Explanation:

#color(red)(sigma) "bonds"# are the formed by the overlapping of the #(s-p)# or, #(s-s)# orbitals by head on overlapping...such as in the picture...

#" "#(P-P) OVERLAPPING

These three types of structure are mainly involved in producing #color(red)(sigma)"bonds"#....which emans single bonds...

But some time we see that there is #C-=C # bonds or, #C=C# bonds...
#" "#Here in the first case ,there is one #sigma# bond but the other bond is the# pi# bond who contains loose electrons but strengthens the whole bond formation...
#" "#In the #2nd# case there is two #pi #bonds... which produces by following type of overlapping(#color(red)("(side-wise overlapping)"#...

my notebook
#" "# (P-P) SIDE-WISE OVERLAPPING

Hope it helps...
Thank you...
