Answer:
number of Carbons = 2 times number of Hydrogens
Therefore, for alkene with 10 carbons, it will have 2 x 10 = 20 hydrogens.
Its chemical formula will be
C10H20
Answer:
Hi
The water molecule is composed of three atoms: an oxygen atom and two hydrogen atoms. Very strong electromagnetic forces hold the atoms inside the molecule.
A parallel electromagnetic attraction exists between the molecules individually. Water molecules are constantly moving and continuously form and break bonds with other molecules. As the temperature rises, the molecules move faster and the bonds weaken, changing their state to gas. This is called the boiling point. At this stage, the distance between water molecules is large and intermolecular bonds are almost non-existent.
Explanation:
The C=O stretch appears as a very sharp and intense peak in an IR spectrum. Since, C=O is a double bond, it appears in the "double bond" region of the IR spectrum, which is typically in the 1500-2000 cm-1 range. More specifically, C=O generally falls in the range of 1650-1850 cm-1. The reason for the range is that there are many types of functional groups that contain a carbonyl (C=O), such as a ketone, aldehyde, amide, or ester. Each of these will have a slightly different value as each stretch will have a different energy due to various factors such as conjugation.
