How is a substituted hydrocarbon created from a hydrocarbon chain?

A substituted hydrocarbon created from a hydrocarbon chain is by replacing at least one hydrogen atom with an atom of another element.


What is a ether?

What scientists thought was in the empty parts of space, until Einstein corrected them. Or an ether can refer to an organic molecule in which two hydrocarbon chains are bonded to an oxygen atom.

A molecule that is short of hydrogen atoms and has a double bond is?

A molecule this is short of hydrogen atoms and has a double bond is H2CCH-. The Lewis structure would be Two H's bonded to a C atom, double bonded to another C atom single bonded to one H. The second C atom has a -1 formal charge.


What is Lewis structure of kno2?

KNO3 is an ionic compound. It is written starting with the K+ ion. Next to it is the plus sign. The NO3 structure has a single N atom in the center. To the right is a doubly bonded O atom and to the right and bottom are singly bonded O atoms. The two singly bonded O atoms have six dots, and the doubly bonded has four dots. This structure is bracketed with a 1- superscript.


Does one atom of carbon bond with four other atoms?

It can, but not always. In Methane, for example, it is bonded to four atoms of Hydrogen. But in Ethylene, each carbon atom is bonded to two atoms of Hydrogen, and share a double bond with each other. In Acetylene, each carbon atom is bonded to one atom of Hydrogen, and are triple bonded to each other. So while it always has four bonds, the bonds don't have to be made with four different atoms.


Why is ethene the smallest unsaturated hydrocarbon molecule?

Ethene may not be the smallest what about ethyne? Ethene, ethylene, is C2H4 Unsaturated hydrocarbon molecules contain double or triple bonds. The smallest will either be ethene C2H4 with one double bond, or ethyne , acetylene, HCCH with one triple bond. Ethyne wins, it has 2 less hydrogen atoms making it the LIGHTEST. Look at the structures in wikipedia and work out which is physically the smallest. I still go with ethyne. Wikipedia Ethene Wikipedia Ethyne


Five carbon atom with one double bond?

One type of molecule would be the unsaturated hydrocarbon pentene, there are number of isomers of this compound.
