The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a <u>functional</u> group.
Functional groups are groups of one or extra atoms with exclusive chemical homes regardless of what's connected to them. The atoms of practical agencies are certain via covalent bonds with one another and with the relaxation of the molecule.
Functional groups include:
- hydroxyl,
- methyl,
- carbonyl,
- carboxyl,
- amino, phosphate,
- sulfhydryl.
An atom or institution of atoms that replaces hydrogen in a natural compound that defines the shape of a family of compounds and determines the properties of the family.

To determine the fraction of carbon in morphine, we need to know the chemical formula of morphine. From my readings, the chemical formula would be <span>C17H19NO<span>3. We assume we have 1 g of this substance. Using the molar mass, we can calculate for the moles of morphine. Then, from the formula we relate the amount of carbon in every mole of morphine. Lastly, we multiply the molar mass of carbon to obtain the mass of carbon. We calculate as follows:
1 g </span></span> <span>C17H19NO<span>3 ( 1 mol / 285.34 g ) ( 17 mol C / 1 mol </span></span> <span>C17H19NO3</span>) ( 12.01 g C / 1 mol C) = 0.7155 g C
Fraction of carbon = 0.7155 g C / 1 g <span>C17H19NO<span>3 = 0.7155</span></span>
Formula : BaI₂. <span>barium iodide</span>
I'm pretty sure that it's fracture, Not sure though
Answer:
=C₄H₄O₂
Explanation:
Given the empirical formula of a molecule, the he the quotient of the molecular mas and and the empirical mass=constant.
84.0 g/mol/mass of(C₂H₂O)=constant
=84/(12×2+1×2×16)
=84/42
=2
Therefore, the molecular formula is (C₂H₂O)₂=C₄H₄O₂
