Question

question 9 4 pts 9. polar molecules are termed: hydrophilic hydrostatic hydrophobic covalent

Explanation:

• Polar molecules have a partial positive and partial negative charge due to unequal electron sharing.
• Hydrophilic means "water - loving". Water is a polar molecule (\(H_2O\) has a bent shape with \(O\) being more electronegative than \(H\), creating a dipole). Polar molecules interact well with water through dipole - dipole interactions.
• Hydrophobic means "water - fearing" and typically refers to non - polar molecules (e.g., hydrocarbons like \(CH_4\) which has a symmetrical tetrahedral shape and no net dipole).
• Hydrostatic refers to fluid at rest (related to pressure in fluids, not molecular polarity).
• Covalent is a type of chemical bond (sharing of electrons between atoms), not a term for molecular polarity in the context of interaction with water.

Answer:

Hydrophilic
