Atoms and Chemical Bonds

Question 1

Hydrogen Bonding

Answer 1

Bonding between negative and positive charges of a molecules’ hydrogen and F, O, or N.

Question 2

Hydrophilic

Answer 2

Polar, soluble molecules.

Question 3

Hydrophobic

Answer 3

Not attracted to water, usually C-C or C-H bonds

ex) fats

Question 4

Carbon Bonds

Answer 4

Forms nonpolar with C and H

Forms polar covalent with O and N

Question 5

Structural Isomers

Answer 5

Different arrangement of C atoms, but same formula

ex) C4H10 can be arranged in two ways

Question 6

Cis/Trans Isomers

Answer 6

Same molecular formula, but differs structure around C=C bond; these bonds are inflexible
Cis-meaning common branches are on the same side
Trans-meaning common branches are on different sides

Question 7

Enantiomers

Answer 7

Molecules containing 4 parts, centered around a C atom. Mirror images of one another
ex) a right hand in a mirror

Question 8

Solubiliity

Answer 8

Small, polar molecules that water can dissolve.

ex)sugar is soluble, starch is too large
