So, let's look at an example of equilibrium in the cookie market and see what happens when things change. Let's say the equilibrium price for a chocolate chip cookie is $3. Here's an example of the supply and demand curves, with an equilibrium price of $3, which is at the intersection of the supply and demand curves.
A sigma bond is the end-to-end overlap of the bonding orbitals, usually hybrid orbitals. The sigma bond is a single bond. A pi bond is the side-to-side overlap of unhybridized p-orbitals. A pi bond, along with a sigma bond form a double bond. A triple bond is two pi bonds and a sigma bond. Take a look at this diagram showing a sigma bond and a pi bond, forming a single bond and a double bond. http://metafysica.nl/ethylene01.jpg.
1 In a single bond between two atoms, it will be only sigma bond, while in a double bond, there are one sigma and one pi bond and in case of triple bond, two pi and one sigma bond exists between atoms. 2  The number of bonding pairs of electrons between two elements is called as bond order. molecule is a group of atoms that are bonded by a chemical bond. The atoms are in a molecule are arranged in a regular pattern. Molecules contain atoms chemically bonded to one another in order to form a definite lattice.
