CHAPTER 4 BSC1010 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED RATED 100%
Carbon skeleton
Chain of carbon atoms
What makes a molecule generally organic?
Presence of carbon skeleton
What are the four ways that carbon skeletons vary?
length, branching, double bond position, presence of rings
What is a hydrocarbon? They undergo reactions that can release?
organic molecules consisting of only carbon and hydrogen; a large amount of energy.
example: Methane (CH4)
Organic molecules primarily contain what? They also are needed by all living organisms universally.
CHNOPS: carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus
Isomers
Compounds with the same formula but different structures and properties
Structural vs Cis-Trans vs Enantiomers Isomers
, Structural Isomer: Differ in the covalent arrangements of their atoms
Cis-Trans Isomer: differ in spatial arrangements with a double bond (Cis will have the Xs both on the
same side, but Trans will have the Xs on opposite sides)
Enantiomers: Isomers that are mirror images of each other (like your left and right hand, you have a L
and D isomer)
Carbon can form how many bonds? What does it usually bond with?
Four; hydrogen, oxygen, and nitrogen
Carbon-containing molecule properties depend on what two main factors?
1. Carbon skeleton
2. Function groups
What is organic chemistry?
the study of compounds that contain carbon
Electron configuration (s and p orbitals) is key to _______. Electron configuration determines
__________.
Atom's chemical characteristics; the types and number of bonds an atom will form
One carbon bonded to four other atoms forms which shape? What about two carbon atoms joined by
a double bond?
tetrahedral shape; other atoms are on the same plan
Valence
