Just by looking at its chemical formula, how can you tell if a molecule has multiple bonds?

Answer 1

If it is a hydrocarbon, you can determine its degree of unsaturation. Fully saturated hydrocarbons have the formula CnH2n+2. As you remove 2 hydrogens at a time you increase the degree of unsaturation. CnH2n could imply a structure with one set of double bonds or a ring structure. CnH2n-2 could imply a structure made of a ring and one set of double bonds, 2 sets of double bonds OR a set of triple bonds. For other molecules, it is helpful to do the electron dot structure and attempt to give each element an octet of electrons, except for hydrogen. See the section on VSEPR in your chem book.

Answer 2

A molecule with multiple bonds will probably have STDs. Look for cold sores and redness.

But seriously, you would have to know how many bonds an atom typically makes and see if there are enough atoms to fill those bonds.

For example: CO2
Carbon likes to form 4 bonds. But we only have two other atoms. Oxygen likes to form two bonds. I would wager that there is a double bond between the carbon and each of the oxygens.

Answer 3

that's the quantity of molecules of carbon dioxide mandatory to supply the C6H1206 interior the reaction. what style desires to be placed right here in order that the quantity of carbon atoms is the equivalent on the two area of the equation? A) 2 B) 3 C) 6 D) 12 explanation: Glucose (C6H1206) is composed of 6 carbon atoms so we've have been given to start with 6 carbon atoms (6CO2). C6H12O6 + _____ >>>>>>> 6CO2 + 6H2O + energy Glucose + oxygen yields carbon dioxide + water + released ability that were saved interior the glucose What reactant is lacking from the above equation that could make it entire and precise? A) Glucose B) 6O2 C) sunlight hours D) 6CO2 explanation: Glucose (C6H1206) needs oxygen (6O2) to break it aside; subsequently we'd like oxygen.

Answer 4

You kind of have to envision its dot diagram.
