ANSWERS WITH COMPLETE VERIFIED SOLUTIONS
LATEST UPDATE
What are the major functional groups found in organic molecules?
Hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl groups
What is an enantiomer?
Isomers that are mirror images of each other
What is a cis-trans isomer?
Isomers that have the same covalent bonds but differ in spatial arrangements
What is a structural isomer?
Isomers that have different covalent arrangements of their atoms
How does carbon skeleton variation contribute to the diversity and complexity of organic molecules?
In an organic compound, a carbon atom could be bonded to as many as 4 other carbon atoms.
Carbon atoms also readily form double and triple bonds.
How do carbon skeletons vary?
Length, branching, double bond position, presence of rings
, Why are hydrocarbon molecules hydrophobic?
They are non polar molecules. The electrons in their carbon-hydrogen bonds are shared equally,
resulting in no positive or negative charges, which prevents them from interacting with polar water
molecules
What are hydrocarbons?
Organic molecules consisting of only carbon and hydrogen
How does carbon's electron configuration account for its ability to form large, complex, and diverse
organic molecules?
Carbon has four valence electrons, which allows it to form four covalent bonds with a variety of atoms
What are the effects of acid precipitation?
Kills vegetation, dissolves marble and limestone
What is the cause of acid precipitation?
The mixing of different pollutants with water in the air
What is acid precipitation?
Precipitation with a pH lower than 5.6
What is pH?
The concentration of hydrogen ions in a solution
What is a base?
A substance that reduces the hydrogen ion concentration of a solution.
