Cemical Bond Notes
| Question | Answer |
|---|---|
| What type of chemical bond involves the sharing of electron pairs between non-metal atoms? | Covalent bond |
| What type of chemical bond forms from the electrostatic attraction between oppositely charged ions, usually a metal and non-metal? | Ionic bond |
| What strong dipole-dipole intermolecular force named after element 1 is responsible for water's high boiling point and surface tension? | Hydrogen bond |
| How many hydrogen bonds form between an adenine and thymine base pair in DNA? | Two |
| How many hydrogen bonds form between a guanine and cytosine base pair in DNA? | Three |
| What structural feature of proteins, such as the alpha helix and beta sheet, is stabilized by hydrogen bonding? | Secondary structure |
| What type of covalent bond formed by side-by-side p-orbital overlap is found alongside a sigma bond in double bonds? | Pi bond |
| What rule in organic chemistry states that a double bond cannot be located at the bridgehead of a bridged ring system? | Bredt's rule |
