What do the little numbers mean in a compound?
The little number you see to the right of the symbol for an element is called a subscript. That number indicates the number of atoms of that element present in the compound.

What does the 2 mean in chemistry?
Chemical Formulas For example, “H” represents one atom of hydrogen and “O” represents one atom of oxygen. If we want to represent two atoms of hydrogen, instead of writing H H, we write H2. The subscript “2” means that two atoms of the element hydrogen have joined together to form a molecule.
How to write an IUPAC name for an organic compound?
STEPS INVOLVED IN WRITING IUPAC NAME 1 The first step in giving IUPAC name to an organic compound is to select the parent chain and assign a word root. 2 Next, the appropriate primary suffix (es) must be added to the root word to indicate the saturation or unsaturation. More
What are the physical properties of organic compounds?
Physical properties of organic compounds typically of interest include both quantitative and qualitative features. Quantitative information includes melting point, boiling point, and index of refraction. Qualitative properties include odor, consistency, solubility, and color.
What is the equation for continuously compounding interest?
The equation for continuously compounding interest, which is the mathematical limit that compound interest can reach, utilizes something called Euler’s Constant, also known as e. Although e is widely used today in many areas, it was discovered when Jacob Bernoulli was studying compound interest in 1683.
Which is the first step in naming an organic compound?
The first step in naming an organic compound is to select the parent chain and give the root word depending on the number of carbons in it. The longest continuous carbon chain containing as many functional groups, double bonds, triple bonds, side chains and substituents as possible is to be selected as parent chain.
