Bonds Flashcards
What type of bond has the transfer of electrons?
Ionic
What type of bond has the sharing of electrons?
Covalent
What determines if atoms will interact?
Size of the nucleus and number of orbitals
To form covalent bonds, atoms have what?
Similar electronegativity
What type of bonds are formed between atoms with very different electronegativities?
Ionic
What type of bond is formed between C and H?
Nonpolar covalent
What type of bond consists of the equal sharing of electrons?
Nonpolar covalent
What type of bond consists of the unequal sharing of electrons?
Polar covalent bonds
What type of bond occurs between C and O?
Polar covalent
In a CO bond, which atom are electrons more likely to be around?
O, because it is more electronegative
What is determined by the number of Nonpolar &/or polar covalent bonds present in covalently bound molecules?
How they will interact with one another
Information concerning the number of Nonpolar &/or polar covalent bonds present in covalently bound molecules determines what ?
Solubility and energy density
What type of biomolecule is very energy dense?
Lipids
What type of bonds make up a majority of lipids?
Nonpolar covalent
what type of bond is NaCl?
Ionic
What makes one water molecule/OH bond interact with another?
the polarity
What makes water the universal solvent?
The polar covalent character of water molecules allows them to interact with other charged atoms
What type of molecules does water not usually interact with?
Nonpolar molecules
Oil is an example of what type of bond?
Nonpolar
Why is carbon found in most biological molecules?
It’s valence of 4 allows it to interact with up to 4 different atoms
What type of bonds are C-C bonds?
Nonpolar covalent
What type of bonds are C-H bonds?
Nonpolar
What type of bond is formed by C binding to other atoms that are not also C or H?
Polar covalent
How are carbon chains usually represented?
R
