"What if" is a sign of a poorly thought out question. It's possible to ask a question that starts with "what if" that can actually be answered, but it's a lot less likely than questions that are more specific.
There are lots of things that could happen if a bond in a particular molecule is a double bond. I'm not going to list them all; I'm going to ask you to reformulate the question so that I don't have to read your mind to find out what it is you want to know.
For example:
"What effects does a double bond have on the physical properties of a fatty acid?" See, that's a question that I could actually give an intelligent answer to. Another would be "How does the rate of (a particular type of reaction; be specific) change if the reaction site of the molecule involved has a double bond instead of a single bond?"
four single bonds two double bonds two single bonds and one double bond one triple bond and one single bond
They have sigma and pi bonds When you have one bond, it's a sigma bond. When you have double bonds, you have 1 sigma and 1 pi bond When you have a triple bond, you have 1 sigma and 2 pi bonds.
The molecule of oxygen has a double bond: O=O.
There is a sigma and a pi bond in a double bond.Single bond has only a sigma bond.
This compound only contains covalent bonds, more descriptively, one double bond and all others are single bonds.

They have sigma and pi bonds When you have one bond, it's a sigma bond. When you have double bonds, you have 1 sigma and 1 pi bond When you have a triple bond, you have 1 sigma and 2 pi bonds.
Every double bond has one pi bond and one sigma bond. There are five double bonds in acetylsalicylic acid, so there are five pi bonds.
one sigma bond and one pi bond
The molecule of oxygen has a double bond: O=O.
There is a sigma and a pi bond in a double bond.Single bond has only a sigma bond.
Sigma bonds are single bonds. pi bonds are double bonds. Ethene has a double bond. So between the two carbons, there is one sigma bond and one pi bond. Between the carbon and hydrogens, there is one sigma bond.
This compound only contains covalent bonds, more descriptively, one double bond and all others are single bonds.
They can each form four bonds.
A double bond is a covalent bond, but not all covalent bonds are double bonds; some bonds may be single or triple (or even in rare cases, quadruple) instead.
1- four single bonds, 2- two single and one double bond, 3- one single and one triple bond, 4- two double bonds.
The bonds in CO2 are double bonds from C to O. The double bonds each have 1 sigma bond and 1 pi bond.
