what is sigma bond..?
Answers
HELLO THERE!
Here's your answer!
On this reference, let me tell you that there are two types of bonds: Sigma bond and Pi bond.
Let's begin with how each are formed. Your answer lies within:
Sigma bond is the bond which is formed by head on overlap of two orbitals. Sigma bond is stronger than the pi bond because head on overlap is more effective. For example, the carbons in an alkane are bonded by a single sigma bond. The sigma bond cannot be broken easily, so we get substitution products in alkanes.
Pi bond is the bond which is formed by side wise overlap of two orbitals, which is not that effective and hence, the pi bond is weaker than the sigma bond. For example, in alkenes, the bond between two carbon atoms contains a sigma and a pi bond. The pi bond is easily broken and hence, addition products are obtained.
Hope it's clear.

Answer:
Explanation:
It is a type of a covalent bond which is formed by head on overlapping of bonding orbitals along the internuclear axis( by default it is taken as z- axis.)
